<?php $array = array('a' => 'foo', 'b' => 'bar', 'c' => 'baz', 'd' => 'yo'); $array = array_merge(array_flip(array(end($array) => key($array))), array_slice($array,1,count($array) - 2), array_flip(array(reset($array) => key($array)))); print_r($array);
Output for 4.3.0 - 7.2.0
Array ( [d] => yo [b] => bar [c] => baz [a] => foo )
