Description:
------------
It would be desirable to add arguments to the callback function during the execution of array_filter(), like so:

<?php

function filterMPEG($line,$extra)
{
    return preg_match("#Codec {$extra}#",$line);
}

$a = array('Filter Low Pass','Codec MP2','Codec MP4');

// output MPEG2 codecs
print_r(array_filter($a,'filterMPEG','MP2');
// output MPEG4 codecs
print_r(array_filter($a,'filterMPEG','MP4');

?>

This is covered in a more general way by closures introduced in PHP 5.3.
