//input array
$array = {

          4 => 1,
          8 => 3,
          9 => 2,

want sum of key for a specific period like 1-5, 6-10

need output like array {1-5 => 6 ,6-10 => 5}

without using foreah

You're aware that the code you have written is not even a valid PHP array right? If you want to use the shorthand syntax it is square brackets `[]` not curly braces `{}` and will only work for PHP 5.4.X and above. — Mike, Nov 20 '13 at 18:32

Try this code.. Not a rocket science..

function sumArray($array, $min, $max) {
   $sum = 0;
   foreach ($array as $k => $a) {
      if ($k >= $min && $k <= $max) {
         $sum += $a;
      }
   }
   return $sum;
}

echo sumArray($array, 1, 5);

Why not? Do you have a good reason for this? I can't think of one. – John Conde Nov 20 '13 at 18:35
@YasirPoongadan are you writing compiler? – zzlalani Nov 20 '13 at 18:36
