Qube @ Efnet preg_find.php

simple glob() type replacement:

$files = preg_find('/./', $dir);

recursive?

$files = preg_find('/./', $dir, PREG_FIND_RECURSIVE);

pattern match? find all .php files:

 $files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE);  

sorted alphabetically?

 $files = preg_find('/\.php$/D', $dir, PREG_FIND_RECURSIVE|PREG_FIND_SORTKEYS);   

sorted in by filesize, in descending order?

$files = preg_find('/./', $dir,
 PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC |PREG_FIND_SORTFILESIZE|PREG_FIND_SORTDESC);
