Read Do not use PHP references by PHP expert Johannes Schlüter

PHP references are a holdover from PHP 4, where objects were passed by value instead of by reference unless you deliberately made them by reference. This isn’t necessary when using PHP 5, because all objects are passed by reference in PHP 5 all the time.

Scalars and arrays are still passed by value by default in PHP 5. If you need to pass them by reference, you should just use an object.
