<?php $arr = array( 1,2,3,4, array("wat" => "watdf8u38472309ufj"), ); $mt = microtime(true); $_arr = eval(utf8_decode(var_export($arr, true))); print microtime(true) - $mt."\n\n"; $mt = microtime(true); $_f = create_function("", "return ".utf8_decode(var_export($arr, true)).";"); $_arr = call_user_func($_f); print microtime(true) - $mt."\n\n"; $mt = microtime(true); $_arr = include "data://text/php,base64;".base64_encode("return ".utf8_decode(var_export($arr, true)).";"); print microtime(true) - $mt."\n\n";

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).
