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.
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
)

- array_intersect() - 배열의 교집합을 계산
- array_intersect_assoc() - 인덱스 검사과 함께 배열의 교집합을 계산
- array_uintersect_assoc() - Computes the intersection of arrays with additional index check, compares data by a callback function
- array_uintersect_uassoc() - Computes the intersection of arrays with additional index check, compares data and indexes by separate callback functions
- array_intersect_key() - Computes the intersection of arrays using keys for comparison
- array_intersect_ukey() - Computes the intersection of arrays using a callback function on the keys for comparison
