array_diff_assocPodręcznik PHPPoprzedniNastępnyarray_diff_assoc (PHP 4 >= 4.3.0)array_diff_assoc -- Computes the difference of arrays with additional index checkDescriptionarray array_diff_assoc ( array array1, array array2 [, array ...]) array_diff_assoc() returns an array containing all the values from array1 that are not present in any of the other arguments. Note that the keys are used in the comparison unlike array_diff(). Przykład 1. array_diff_assoc() example<?php $array1 = array ("a" => "green", "b" => "brown", "c" => "blue", "red"); $array2 = array ("a" => "green", "yellow", "red"); $result = array_diff_assoc ($array1, $array2); /* The result is: Array ( [b] => brown [c] => blue [0] => red ) */ ?> In our example above you see the "a" => "green" pair is present in both arrays and thus it is not in the ouput from the function. Unlike this, the pair 0 => "red" is in the ouput because in the second argument "red" has key which is 1. Two values from key => value pairs are considered equal only if (string) $elem1 === (string) $elem2 . In other words a strict check takes place so the string representations must be the same. Notatka: Please note that this function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using, for example, array_diff_assoc($array1[0], $array2[0]);.
