<?php function vassertf($format, array $args) { return (bool) @vsprintf($format, $args); } var_dump(vassertf('Too many %s placeholders %s', ['foo'])); var_dump(vassertf('Not enough placeholders', ['foo'])); var_dump(vassertf('Correct number of %s placeholders', ['foo']));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
