array_intersect_uassoc

(PHP 5, PHP 7)

array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function

설명

array array_intersect_uassoc ( array $array1 , array $array2 [, array $... ], callable $key_compare_func )

array_intersect_uassoc() returns an array containing all the values of array1 that are present in all the arguments. Note that the keys are used in the comparison unlike in array_intersect().

인수

array1: Initial array for comparison of the arrays.
array2: First array to compare keys against.
...: Variable list of array arguments to compare values against.
key_compare_func: 이 비교 함수는 첫번째 인수가 두번째 인수보다 작거나, 같거나, 클 경우에 각각 0보다 작거나, 같거나, 큰 정수를 반환해야 합니다.

int callback ( mixed $a, mixed $b )

반환값

Returns the values of array1 whose values exist in all of the arguments.

예제

Example #1 array_intersect_uassoc() example


<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");

print_r(array_intersect_uassoc($array1, $array2, "strcasecmp"));
?>

위 예제의 출력:

Array
(
    [b] => brown
)
