If you're not looking to duplicate the rest of the string, but instead just want the offset, in the spirit of the str*pos() functions, use strcspn()

A little modification to Evan's code to use an array for the second parameter :
<?php
function strpbrkpos($s, $accept) {
$r = FALSE;
$t = 0;
$i = 0;
$accept_l = count($accept);
for ( ; $i < $accept_l ; $i++ )
if ( ($t = strpos($s, $accept[$i])) !== FALSE )
if ( ($r === FALSE) || ($t < $r) )
$r = $t;
return $r;
}
?>
