<?php $mem[1]["start"] = (memory_get_peak_usage(true)/1024/1024); $arr = [ "c" => [ "d" ], "d" => [], ]; $arr["d"] =& $arr["c"]; $mem[1]["end"] = (memory_get_peak_usage(true)/1024/1024); var_dump($arr); var_dump($mem);

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).
