run code in 300+ PHP versions simultaneously
<?php $array = [ ["firstname" => "John", "lastname" => "", "email" => "", "uri" => ""], ["firstname" => "", "lastname" => "Smith", "email" => "", "uri" => ""], ["firstname" => "", "lastname" => "", "email" => "john@example.org", "uri" => ""] ]; $result = array_shift($array); // remove the first row and push it into the result array foreach ($array as $row) { $result = array_merge($result, array_filter($row, 'strlen')); // merge only non-empty elements into the result } var_export($result);

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).
