Please note, the correct function synopsis is:
array array_uintersect_uassoc ( array array1, array array2 [, array ...], callback data_compare_func, callback key_compare_func)
You may specifiy as many arrays as you like, but the last two parameters must be valid call back functions.
array_uintersect_uassoc
(PHP 5)
array_uintersect_uassoc — Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions
說明
array array_uintersect_uassoc
( array
$array1
, array $array2
[, array $...
], callable $value_compare_func
, callable $key_compare_func
)Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions Note that the keys are used in the comparison unlike in array_uintersect(). Both the data and the indexes are compared by using separate callback functions.
參數
-
array1 -
The first array.
-
array2 -
The second array.
-
value_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。
-
key_compare_func -
Key comparison callback function.
回傳值
Returns an array containing all the values of
array1 that are present in all the arguments.
範例
Example #1 array_uintersect_uassoc() example
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");
print_r(array_uintersect_uassoc($array1, $array2, "strcasecmp", "strcasecmp"));
?>
上例將輸出：
Array
(
[a] => green
[b] => brown
)
