array_intersect_key with three array in php

Question

I have three array from dynamic data in php for example :

array1 = array('10-11-2015'=>23.6,

               '25-11-2015'=>48.6,

               '12-11-2015'=>14.52);



array2 = array('10-11-2015'=>8.7,

               '22-10-2015'=>86.6,

               '12-11-2015'=>78.5);



array3 = array('10-11-2015'=>5.8,

               '19-09-2015'=>3.6,

               '12-11-2015'=>96.4);

I just need common keys from this three array

newarray = array('10-11-2015','12-11-2015');

I use

array_intersect_key

but it is for only two array.

How I can get it form three or more array ?

Something like this?

array_keys(array_intersect_key($array1, $array2, $array3));
