Getting total value of an array with condition

Question

I need to get the total value of this array of all the numbers above or equal to 0. This is the array

$aReeks = array(23,245,1,2,12,-10,46,6,66,9999,-55,348,56,6         


        

Answer 1

Here's a quick way:

$total = array_sum(array_filter($aReeks, function($n) { return $n > 0; }));

• Filter the array for values greater than 0
• Sum that array

Oh I now see the "I have to do it with a for loop.", so this won't be accepted for your homework I imagine.
