run code in 300+ PHP versions simultaneously
<?php $min = 17; $max = $min + 48; // 48 is to fit the results in my console for ($testseed=$min; $testseed<$max; $testseed++) { mt_srand( $testseed ); $r = rand(); printf( "rand() == 0x%08x == %d\n", $testseed, $r ); } ?>

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).
