array_intersect_uassoc
(PHP 5)
array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function
說明
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().
參數
-
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 -
在第一個參數小於、等於或大於第二個參數時，該比較函式必須相應地回傳一個小於、等於或大於 0 的整數。
回傳值
Returns the values of array1 whose values exist
in all of the arguments.
範例
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"));
?>
上例將輸出：
Array
(
[b] => brown
)
