frankenphp's Introduction

FrankenPHP: Modern App Server for PHP

FrankenPHP is a modern application server for PHP built on top of the Caddy web server.

FrankenPHP gives superpowers to your PHP apps thanks to its stunning features: Early Hints, worker mode, real-time capabilities, automatic HTTPS, HTTP/2, and HTTP/3 support...

FrankenPHP works with any PHP app and makes your Laravel and Symfony projects faster than ever thanks to their official integrations with the worker mode.

FrankenPHP can also be used as a standalone Go library to embed PHP in any app using net/http.

Learn more on frankenphp.dev and in this slide deck:

Getting Started

Docker

docker run -v $PWD:/app/public \
    -p 80:80 -p 443:443 -p 443:443/udp \
    dunglas/frankenphp

Go to https://localhost, and enjoy!

Tip

Do not attempt to use https://127.0.0.1. Use https://localhost and accept the self-signed certificate. Use the SERVER_NAME environment variable to change the domain to use.

Standalone Binary

If you prefer not to use Docker, we provide standalone FrankenPHP binaries for Linux and macOS containing PHP 8.3 and most popular PHP extensions: Download FrankenPHP

To serve the content of the current directory, run:

./frankenphp php-server

You can also run command-line scripts with:

./frankenphp php-cli /path/to/your/script.php

frankenphp's Issues

Death of worker causes panic

I attempted a very simple implementation of restarting a worker on a file change:

<?php

$startup = hash_file('crc32', __FILE__);

do {
    $running = frankenphp_handle_request(function (): void {
        echo "hi!!";
        var_dump(hash_file('crc32', __FILE__));
    });
    if (hash_file('crc32', __FILE__) !== $startup) {
        error_log('rebooting');
        die();
    }
} while ($running);

This causes a panic in frankenphp:

(worker): unexpected termination

Hi Dunglas 👋🏻

First, thanks for this new SAPI, amazing to see how PHP can be improved for future applications.

Small issue that I'm facing while using the worker mode, I followed the documentation for the Symfony application then launched it using Docker:

docker run \
    -e FRANKENPHP_CONFIG="worker ./public/index.php" \
    -v $PWD:/app \       
    -p 80:80 -p 443:443 \
    dunglas/frankenphp
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

# ...

First, it seems that the v8 version is not automatically pulled, is there any issue using an arm64 image (I'm on M1 chip)?

Second, when launched (it launched even with the warning message, it seems that it cannot be started correctly:

{"level":"info","ts":1665988244.9370515,"msg":"using provided configuration","config_file":"/etc/Caddyfile","config_adapter":""}

{"level":"error","ts":1665988250.9677563,"msg":"unexpected termination, restarting","worker":"/app/public/index.php"}

I'm not sure why it tries to restart the worker (maybe it's due to the arm64 architecture?) but the application does not respond 🙁

Thanks for the help and sorry for this issue 😄

On unexpected shutdown, handoff connection to a another worker

I've noticed that if a worker dies due to OOM (due to a memory leak, for example), it should be possible to send the request to another thread. I think this should only happen for GET requests. Is this a good idea?

per project Caddyfile SERVER_NAME override?

I am able to change {$SERVER_NAME:localhost} to {$SERVER_NAME:demo.localhost} in caddy/frankenphp/Cadyfile and it works. This way my url matches my Laravel .env APP_URL setting.

Is is possible to have that setting pulled from a project level Caddyfile or preferably from a .env file instead of hard coded into the image?

Rebuild for 8.2.3

I kicked off a new build in GitHub Actions to pick up 8.2.3 which contains security fixes.

Consider renaming DEBUG env var

In the built-in Caddyfile, there is a built-in DEBUG env var injected. This is quite generic and may conflict with other frameworks or applications. Perhaps we should call it FRANKENPHP_DEBUG?

Windows compatibility

Currently this project is compatible with Linux and macOS (and likely with other UNIXes such as FreeBSD), but it hasn't been tested on Windows.

It would be nice to make it compatible for Windows and provide some binaries for this platform.

Starting with a basic file cannot execute

Start the docker and open the webrowser at https://localhost, accept "the risk".

The following message occurs:

Version Number for Frankenphp (frankenphp version cmd)

Hello,

I would like to work on e.g. an alpine package for a testing build for frankenphp. But this requires a version number for frankenphp.

Edit:

/usr/src/app $ frankenphp version
v2.6.2 h1:wKoFIxpmOJLGl3QXoo6PNbYvGW4xLEgo32GPBEjWL8o=

This looks like the caddy version https://github.com/caddyserver/caddy/releases/tag/v2.6.2 . Can I use this? Or will there be specific git tags on frankenphp available?

Best regards

runtime missed error

When I try to launch a Symfony project in worker mode without installing the runtime/frankenphp-symfony library, I have this line in a loop into the log
{"level":"error","ts":1668116008.9931438,"msg":"unexpected termination, restarting","worker":"/app/public/index.php"}

To reproduce:

symfony new --full test
cd test
docker run --rm -e FRANKENPHP_CONFIG="worker ./public/index.php" -e APP_RUNTIME=Runtime\\FrankenPhpSymfony\\Runtime -p 80:80 -p 443:443 -v $(pwd):/app dunglas/frankenphp

To solve:

symfony composer req runtime/frankenphp-symfony

Is worker mode broken???

PHP file

// public/worker.php
<?php

do {
	$running = frankenphp_handle_request(
		function () {
			echo "hello world";
		}
	);
} while ($running);

Then:

docker run --rm -e FRANKENPHP_CONFIG="worker ./public/worker.php" -p 80:80 -p 443:443 -v $(pwd):/app -w /app dunglas/frankenphp

When I curl localhost, it just hangs forever. @dunglas, can you reproduce this or am I doing something wrong?

Consider implementing fastcgi_finish_request()?

fastcgi_finish_request is often used to perform operations after a request is completed (such as sending an email). Should FrankenPHP implement this and/or create a similar function? There are pro/cons to implementing it with the same name (it will "just work" with existing code), and a con would be that if there are any differences in behavior, then things may not work as expected or code may use the existence of that function as a sentinel that it is running in a fastcgi context and do unexpected things.

I'd be happy to tackle implementing this, whatever is decided.

Proposal: remove automatic exceptions handling

Currently, in worker mode, FrankenPHP automatically catches exceptions: https://github.com/dunglas/frankenphp/blob/main/frankenphp.c#L187-L196

Exceptions would be better handled in userland. This would simplify Franken's PHP code and make its behavior more predictable. AFAIK, other runtimes with a worker mode (RoadRunner) don't automatically handle exceptions as well.

Symfony never throws in worker mode: symfony/symfony#45997

WDYT @Nyholm, as you have a good experience of what is expected in these cases?

How are shutdown functions called?

Consider the following code:

register_shutdown_function(function() { error_log('outside'); });

do {
    $running = frankenphp_handle_request(function (): void {
        register_shutdown_function(function() { error_log('in request'); });
    });
} while ($running);

Nothing is output in the logs that I can see (tested SIGTERM, SIGINT to stop the server):

Are shutdown functions called per request/worker/ever? (I could probably do a db insert or something to see for sure.)
Should shutdown functions be contextual on workers (such as in the example)?

A number of frameworks/libraries use shutdown functions to trigger things after a request (I've abused them to process queues, I think WordPress uses them to process cron jobs, error reporting, etc). It'd also be useful to do things when the worker itself dies (outside the loop) though, but in most cases shut down functions are registered with an expectation of request ending.

How to install php extensions?

Installing a php8.2-{extension} and moving the .so into /usr/local/lib/php/extensions/no-debug-zts-20220829 will end up with a core_symbols error.

Running on a different port redirects to :80

Run a different port is very convenient for development as it does not require to run with sudo and does not conflict with existing server.

However running the following does not up so well:

docker run -v $PWD:/app/public \
    -p 8080:80 -p 443:443 \
    dunglas/frankenphp

shoud allow to open a browser and read the app from http://localhost:8080.
However we get redirected to https://localhost.

Create integration tests

We currently build docker images in each PR but don't use them. We can, however, use those images and example repos like dunglas/frankenphp-drupal, dunglas/frankenphp-wordpress, etc. to spin up integration tests with "real world" code and verify (at least) a lack of seg-fault. The idea is to run it manually before merging (I imagine these tests will take a while to run).

Perhaps we can use something like dapr/mechanical-markdown to script it?

Globals leak out of request in worker mode

Probably related to #85.

Take the following code:

<?php

do {
	$running = frankenphp_handle_request(
		function () {
			global $global;
			echo $global ?? 'no global';
			$global = 'global';
		}
	);
} while ($running);

After a worker does the first request, "global" will be output instead of "no global" which I (personally) wasn't expecting. Is this expected? I was under the expectation that super-globals are always reset (at least that is what it looks like is going on in the docs).

License

Hi,

looks like there is currently no license. Could you please add one?

Thanks

ARM64 container image

Running this on an Apple M1 chip give the following warning:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

Would be useful to have ARM variants of the container image.

Flaky TestConnectionAbortFinish test

It looks like we have a flaky test @withinboredom:

    frankenphp_test.go:505: 
        	Error Trace:	/go/src/app/frankenphp_test.go:505

https://github.com/dunglas/frankenphp/actions/runs/3480116840/jobs/5819499909#step:5:4347

I also (rarely) get this error locally.

PHPStorm cannot use xdebug

This is probably on PHPStorm, but it fails to do remote step debugging because $_SERVER['SERVER_PORT'] is unset.

From looking at the code around https://github.com/dunglas/frankenphp/blob/main/cgi.go#L126, it looks like it should be set, but a simple var_dump($_SERVER) shows that it is indeed, not set.

Support for max_execution_time and max_input_time

max_input_time and max_execution_time are currently disable as they conflict with ZTS.

PHP will need to be improved if we want to support these options: https://externals.io/message/118859

Idea: Memcached client in golang with request pipelining

For https://memcached.org/ servers or proxies

This may be out of scope.

Motivation

Memcached is heavily used in some web applications for caching state or the results of expensive operations (db queries, results of reading data from web services, etc)
If there are hundreds of workers, it'd reduce cpu and memory resource usage and syscalls if they shared a small finite number of memcache connections (pool)

(unless there are ~32+ cpu cores, 1 connection may suffice)
Both golang and php could use the same client, allowing moving method implementations to/from golang (e.g. check a json array for a value, add a value)
- (or read/write with serializers such as PECL msgpack, etc. https://msgpack.org/ has many implementations. )
- Though this could go in its own PECL, the ability to share the same client is useful

Benchmarking notes

Request pipelining does better when there is actual network latency (https://github.com/twitter/twemproxy/#pipelining) (e.g. non-pipelined golang clients would be limited to 1000 requests per second with 0.001 second network latency)
https://github.com/twitter/twemproxy/ has performance issues when clients pipeline requests. Reduce mbuf size with -m $MBUF_SIZE if this is configured to connect to a twemproxy proxy
I haven't benchmarked this yet.

Background

It would be extremely useful to have compatibility with the memcached flags int used to indicate the chosen serializer https://github.com/php-memcached-dev/php-memcached/ (source of http://pecl.php.net/memcached )

Years ago, I implemented a pipelining memcached client, and embedded it in https://github.com/TysonAndre/golemproxy#about for a hackathon (it should work and has unit tests, but I never had time to try it)
I believe the pool config syntax in that codebase is compatible with https://github.com/twitter/twemproxy/#pipelining

The memcached client this uses is based on https://github.com/bradfitz/gomemcache

This rewrites parts of it and adds pipelining support to that library.

Alternatives

Use existing memcached or memcache PECL normally

Cache (Twig) is not regenerated in dev mode

Hi, I use the FrankenPHP demo with the worker mode. If we modify a Twig template (with the dev env), docker has to be restarted, so the changes are taken in account. Is it a limitation of the worker mode?

And even if we clear the cache manually, we still have to restart FrankenPHP so see the new changes.

Docker image quite heavy : remove build deps ?

Hello,

It seems that Docker image is quite heavy (around 700MB).

I looked at the Dockerfile (https://github.com/dunglas/frankenphp/blob/main/Dockerfile) and it seems that $PHPIZE_DEPS are never removed where as in think they are not needed after PHP and go compilation ?

I built the image removing these deps for testing but I have a problem with composer (I'll fill an issue about that too!)

Enabling/adding PHP extensions

What is the best way to add PHP extensions? Once approach I enjoy from Bref is how it includes the extensions but disables them. Are there plans to include enabling/disabling extensions like Postgres?

WordPress?

Can this run WordPress also or is it targeting custom symphony applications only?

Go's garbage collector and load (benchmarks)

While doing some load testing and comparing frankenphp to apache and fpm, I noticed that a single gc cycle from golang can screw up everything.

Here's apache:

Here's fpm:

And here's frankenphp:

and the average graph to show the gc:

This is mostly to document this behavior and if benchmarking is desired, take note to tune two environment variables:

GOGC: "a parameter that picks a point in the GC CPU and memory trade-off. The key takeaway is that doubling GOGC will double heap memory overheads and roughly halve GC CPU cost, and vice versa." A value of 512 will get you approx 2-3 minutes @ 200 rps before running into 2-3s stop-the-world gc pauses. If you're doing benchmarks, and not considering memory usage, setting it "off" might be worth considering, with a noted caveat that "memory/gc tuning will be required to achieve these values long-term."
GOMEMLIMIT: the maximum amount of memory to use. Due to the overhead of caddy, Go VM, and frankenphp, it should be larger than the PHP memory limit.

Setting GOGC=off GOMEMLIMIT=4096 gives me nearly 8 minutes at full load before a GC pause. Take note that this is mostly an issue when load testing specifically. During normal usage, it is unlikely for every single thread to be in use and Go will coordinate these threads to perform a GC. When under load, there is no choice but to affect every request. In the "real world" if every server is running at 100%, there are bigger problems to worry about, so please ensure to remove these pauses from your benchmark to reflect real-world maximums in a perfectly tuned or bursty environment.

See this guide for more information about how these parameters work.

Can frankenphp be embedded in another Go app

Hello,

A bit new here, but I am wondering if Frankenphp can be embedded inside another Go app that is being developed to have its own PHP server running as well?

Thanks

flush() doesn't appear to work

Example code:

<?php

echo "hello";
flush();
sleep(2);
echo "world";

Frankenphp should send hello, then 2 seconds later send world. However, we end up with no response sent for 2 seconds, then helloworld sent all in one go.

Consider increasing # of default workers?

Currently, there is one worker spawned per core (if I'm understanding correctly).

This severely limits concurrent connections as it appears only one request per worker can be handled at a time.

Changing this to 2x dramatically affects the techempower benchmarks:

from:

        {
          "latencyAvg": "421.56ms", 
          "latencyMax": "3.65s", 
          "latencyStdev": "766.41ms", 
          "totalRequests": 74185, 
          "startTime": 1671386842, 
          "endTime": 1671386858
        }

        {
          "latencyAvg": "100.05ms", 
          "latencyMax": "1.01s", 
          "latencyStdev": "137.47ms", 
          "totalRequests": 112578, 
          "startTime": 1671387704, 
          "endTime": 1671387719
        }

Anything beyond 2x has diminishing returns in my testing. FWIW, 2x on my hardware is 32 workers.

Session handling not working in worker mode

I'm trying to use a bigger Symfony application in worker mode. If the caches are warm, it generally works as long as no session is used.
If I visit actions containing e.g. flash message

<div class="flashbags container">
    {% for type, messages in app.flashes %}
        ...
    {% endfor %}
</div>

I get this:

<b>Fatal error</b>:  Uncaught RuntimeException: Failed to start the session. in /app/vendor/symfony/http-foundation/Session/Storage/NativeSessionStorage.php:186

Ships by default the PG driver?

It would be nice to have the PG driver in the default docker image.

How to use this outside of docker?

Hi,

Thank you very much for the amazing work done. I really wanted to use Nginx Unit but lack of gzip compression prevents me from using it. I have no complaint with Caddy as it supports all the features I need. Now I can use FrankenPHP to enjoy faster performance like Nginx unit because of vertical integration with PHP without missing the features and ease of Caddy.

I am using Caddy compiled with Cloudflare DNS Module right now with PHP-FPM. I am not using Docker. How do I use this without docker? Will there be any performance improvement for wordpress websites? I understand they won't run in worker mode and only benefit I'll get is easy integration here. Please let me know. Thanks again!

ssl

im getting ERR_SSL_PROTOCOL_ERROR
is there a way to server files with working ssl?
i want to use public ip or able to link it behind cloudflare with domain

I thought it was related to install-php-extensions script but as it's working properly with php:8.2-apache, I guess it's somewhat related to FrankenPHP specificity. My guess is that the script is not FrankenPHP ready and there are some differences to investigate?

Thank you

Congrats on FrankenPHP

It REALLY sounds and looks like a very promising PHP Framework!

Thumbs Up!

Worker mode uses wrong path

Hi, thanks for the quick fix for #104!

I am now one step further, as in: the server now redirects and responds correctly, but it doesn't serve the file I gave it in the command line.

Running this command with the latest (sha-878a30d) image:

docker run --rm -e FRANKENPHP_CONFIG="worker ./example/worker.php" -p 80:80 -p 443:443 -v $pwd:/app -w /app dunglas/frankenphp

and this worker.php file:

<?php
// ./example/worker.php

do {
    $running = frankenphp_handle_request(
        function () {
            echo "hello world";
        }
    );
} while ($running);

Results in this output:


Warning: Unknown: Failed to open stream: No such file or directory in Unknown on line 0

Fatal error: Failed opening required '/app/public/worker.php' (include_path='.:/usr/local/lib/php') in Unknown on line 0

So I assume the public path is hardcoded somehow? Which path do I need to give it in the FRANKENPHP_CONFIG value for the worker mode?

Random PHP errors when in worker mode (extremely rare)

I'm seeing random (but extremely rare: <0.5% of requests) fatal PHP errors in worker mode:

Cannot instantiate interface from
Cannot instantiate trait from
Cannot instantiate enum
Cannot instantiate abstract class

There's no interface or trait specified in the error, just to be clear, those errors are the literal messages given. The error occurs on random lines/files.

This never happens outside of worker mode and I cannot reproduce it in a smaller sample.

The relevant error messages are coming from these lines in php-src. It smells like some memory shenanigans but it isn't clear if it is a frankenphp bug or a PHP/extension bug.

Create binary releases in addition to Docker images

We can use GoReleaser to build both and also provide .deb, .rpm, etc: https://goreleaser.com/cookbooks/cgo-and-crosscompiling/

WDYT @withinboredom @back-2-95?

Specific PHP version tagging

It's unclear from the docker tags which PHP version I would be getting.

I think for adoption it'd be good to be specific about this, even if you only want to be building 8.2, make an :php-8.2 tag so that when you update to 8.3 people can stick on the older version

cURL error 28: Operation timed out after 10000 milliseconds with 0 bytes received

Wordpress REST API seems to fail because cURL times out after 10 seconds.
I noticed some comments that timeouts are broken because FrankenPHP uses ZTS? (probably for performance reasons?
)
I tried editing the Caddyfile main block and adding a timeouts directive in the frankenphp block but it doesn't seem to affect the error.

Can someone point me in a solvable direction?

Pontential memory leak in worker mode

When PHP is compiled with the --enable-debug flag, a potential memory leak is reported in worker mode when running the tests:

go test -v

[Fri Oct 21 08:21:09 2022]  Script:  '-'
/Users/dunglas/workspace/php-src/Zend/zend_hash.c(279) :  Freeing 0x000000012aa5e000 (56 bytes), script=-
Last leak repeated 3 times
=== Total 4 memory leaks detected ===

I tried to track the potential leak with Valgrind but didn't find anything obvious yet.

Alpine image

I just re-did Dockerfile with alpine images:

From 2.51 Gb (Bullseye) to 256 Mb (Alpine)

I need to cleanup my work and create PR.

Error while trying to start the local server

Posted from SymfonyCon 😉

I was trying to make a local run for my project https://github.com/florentdestremau/symfonycon-turbo and by following the docs, it doesn't work 😬 It goes into an infinite log as seen below. I ended up cancelling the command with ctrl + C, and even then I had to cancel twice.

Using Fibers causes epic crash

Minimal code to reproduce:

<?php

do {
    $running = false;
    //$running = frankenphp_handle_request(function (): void {
        $fiber = new Fiber(function() {
            echo "Starting Fiber\n";
        });
        $fiber->start();
    //});
} while ($running);

With some slight modifications, it can also be reproduced in worker mode.

Server hangs forever

I am using the same setup as described in #100 and the request just hangs indefinitely. Any idea what I can do?

Also, but unrelated to this issue: is it possible to stop the server using ctrl+c? I always have to delete the container through Docker Desktop...
