This is not a bug. Your function invocation is incorrect. I believe what you meant is

$var = filter_var($string_to_filter, FILTER_VALIDATE_REGEXP, array('options' => array('regexp' => '/^something$/')));

Hi,

Thanks for this, I basically completely misunderstood what this function was supposed to do. I thought it validated a regex string (i.e was it a valid regex), not that it validated an input string matched a particular regex.

Whoops!
