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;
}

?>
