vsprintf() accepts arrays with any keys, so the array_shift() technique is unnecessary when writing a printf-type function. Any parameters you require are easily unset from the array you retrieve with func_get_args():

<?php

function mysprintf($format) {
    $args = func_get_args();
    unset($args[0]); /* get rid of "$format" */
    return vsprintf($format, $args);
}

/* I use this technique in production code as follows: */
function logf($target, $string) {
    $args = func_get_args();
    unset($args[0], $args[1]);
    fprintf($GLOBALS['config']['logtargets'][$target],
        "[%s] %s\n", date('H:i'), wordwrap(vsprintf($string, $args), 75, '\n\r '));
}

/* e.g.:
    logf(DEBUG, "Oops! %s", mysql_error());
 */

?>

array_shift() and other costly array operations aren't required, as far as I know. I could be wrong.
