<?php $array = Array( '0' => Array('id' => '5', 'class' => 'A'), '1' => Array('id' => '53', 'class' => 'B'), '2' => Array('id' => '2', 'class' => 'C'), ); foreach ($array as $key => $values) { $array[$key]['description'] = 'dadadadad'; if ($values['class'] == 'B') { $array = array_intersect_key($array, array_flip(Array($key))); } } print_r($array);

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).
