<?php $element = array( 0 => array( 'name' => 'test', 'email' => 'aaa@example.com' ), 1 => array( 'name' => 'testing', 'email' => 'aaa@example.com' ), 1 => array( 'name' => 'Jane Doe', 'email' => 'asd@example.com' )); $array = array_map(function($element) { return $element['name']; }, $element); $array2 = (array_count_values($array)); print_r($array2);

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).
