run code in 200+ php & hhvm versions
Bugs & Features
<?php $e = '\\a\\b\\c\\d'; $e = 'asfdhjadfhj'; var_dump(strrchr($e, '\\')); echo ltrim(strrpos($e, '\\') !== false ? strrchr($e, '\\') : $e);

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
