run code in 300+ PHP versions simultaneously
<?php $bad_char = "♥"; $error_msg = "Illegal usage: $bad_char"; $code = "I \$♥ PHP"; if ( mb_strpos( $code, $bad_char) ) { exit( $error_msg ); } class Test{        const ♥ = "love"; } $obj = new ReflectionClass( "Test" );    if ($obj->getconstant( $bad_char )) echo 'bad char';       

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).
