Getting highest even number out of an array

Question

I need to get the greatest even number out of this array with a for-loop. I know how to get the highest number from the loop, but it\'s not even.

This is the code I have

Answer 1

To find the highest odd number inside an array, you can use array_filter and max.

$aReeks = array(23,245,1,2,12,-10,46,6,66,9999,-55,348,56,6,66,983); 
echo(max(array_filter($aReeks, function($var){return(!($var & 1));})));
//348

If you just need to find if a number is even or odd, you can use:

//if Even Number
$number = "222";
if(!($number & 1)){...}

//if Odd Number
$number = "221";
if($number & 1){...}
