    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;
    }

    ?>
