How to cross 2 arrays in php?
I have 2 arrays with the same number of values and i want to sum them in a cross way.<br>
For example:

$arr1 = array(1,2,3,4);<br>
$arr2 = array(8,7,6,5); 

The result would be:
6,8,10,12
(Meaning: 1+5, 2+6, 3+7, 4+8)<br>
$arr1 Value 0 + $arr2 value 3<br>
$arr1 Value 1 + $arr2 value 2<br>
And so on...

How can i do this?<br>
Thank you
