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

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).
