<?php var_dump( $conv = mb_convert_encoding( $bin = hex2bin("00"), "UTF-8", "UTF7-IMAP" ), mb_check_encoding($bin, "UTF7-IMAP"), bin2hex(mb_convert_encoding($conv, "UTF7-IMAP", "UTF-8")) );

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).
