run code in 300+ PHP versions simultaneously
<?php $array1 = array( 'k' => array( 2 => 100, 98 => 200, ) ); $array2 = array( 'k' => array( 64 => 300 ) ); $array3 = array_merge_recursive( $array1, $array2 ); echo '<pre>'; var_dump( $array3 ); echo 'count: '.count( $array3['k'] );

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).
