Parameter 1 to MongoCollection::insert() expected to be a reference, value given about mongo-php-adapter HOT 5 CLOSED

OK，I solved it. If we need insert or save data to db, we add the reference to the first param.

            if (PHP_VERSION_ID > 70000 && in_array($method, ['insert', 'batchInsert', 'save'])) {
                $saveData = array_shift($param);
                $saveParams = array_shift($param);
                if (NULL==$saveParams) {
                    $saveParams = [];
                }
                $re = call_user_func_array([$collection, $method], [&$saveData, $saveParams]);
            } else {
                $re = call_user_func_array([$collection, $method], $param);
            }

@glowdan can you please elaborate more ? Where did you add this patch ?

I'm using https://github.com/jenssegers/laravel-mongodb with Laravel 4.2.x along with PHP7.0, and this is the only step I'm struggling with.

Unfortunately, insert, batchInsert and save can't be implemented the way they were in the legacy driver:

The insert, batchInsert, and save methods take the first argument by reference. While the original API does not explicitely specify by-reference arguments it does add an ID field to the objects and documents given.

I had the choice:

1. have the first argument by-value: this would have allowed passing a value to the method but the array will be lacking the _id value that is added by the driver
2. have the first argument by-reference: this would fix the _id problem but the method signatures would be incompatible.

The original intent of the driver was to have the argument by-reference so that an auto-generated ID could be added. Thus, I settled for option #2, knowing that people can either handle that specific warning in an error handler or ignore it. On the other hand, having code break because you were expecting an _id field in your array seems a lot more severe.

TL;DR: I wouldn't recommend it.
