array1

The first array.

array2

The second array.

value_compare_func

The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

key_compare_func

Key comparison callback function.

Returns an array containing all the values of array1 that are present in all the arguments.
