I have 2 arrays like this.
Array
(
[14] => 1
[15] => 1
[13] => 2
)
Array
(
[14] => 1
[15] => 1
[13] => 2
)
Here array key and value are same. If array key or value is different, I have to return error value. Like the second array is
Array
(
[12] => 1
[15] => 3
[13] => 2
)
2 arrays should be unique. If key or value not unique, it should return error.
$k=array_intersect($CARTS,$store_cart);
