說明
array array_uintersect_assoc
( array
$array1
, array $array2
[, array $...
], callable $value_compare_func
)Computes the intersection of arrays with additional index check, compares data by a callback function.

參數
-
array1 -
The first array.
-
array2 -

$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");

?>
上例將輸出：
