run code in 300+ PHP versions simultaneously
<?php $♥ = "love"; $pat = "[♥]+"; $sub = "heart"; $code = mb_ereg_replace( $pat, $sub, "I \$♥ PHP" ); echo $code; echo eval($code);

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).
