jsmin - PHP extension for JavaScript minification

Master:

Introduction

This extension adds Douglas Crockford's jsmin functionality to PHP.

http://www.crockford.com/javascript/jsmin.html

Requirements

This extension currently works with PHP 5.3+. Support for older verisons of PHP is not provided.

Installation

Via PECL

You can install this extension by using the pecl command:

pecl install jsmin-beta

Note: Since this extension is currently in beta, you should provide the -beta suffix after the package name.

Via source

To install via source, clone this repo and then run the following:

$ cd /path/to/source
$ phpize
$ ./configure
$ make install clean

Then, move the built module to your extensions directory.

Enable extension

You will want to enable the extension in php.ini by adding:

extension="jsmin.so"

Usage

Using jsmin is simple.

Function: jsmin

Use this function to minify JavaScript. It accepts a single string argument.

<?php

$javascript = <<<JS
/**
 * My JavaScript Library
 */

var notes = "jsmin is easy!";
JS;

echo jsmin($javascript);

Example output is the following:

var notes="jsmin is easy!";

Function: jsmin_last_error

Returns error code of last call to jsmin().

Function: jsmin_last_error_msg

Returns an error message (string) for the last call to jsmin().

Constants

• JSMIN_ERROR_NONE - No errors.
• JSMIN_ERROR_UNTERMINATED_STRING - Unterminated string.
• JSMIN_ERROR_UNTERMINATED_COMMENT - Unterminated comment.
• JSMIN_ERROR_UNTERMINATED_REGEX - Unterminated regex.

Credits

Discovery Communications developed a similar extension in-house for minifying bundled JavaScript.

I decided to take the most recent source from Douglas Crockford's JSMin and port / manage the extension for PECL.
