PHP do every x time something else in a foreach loop

Question

As the title says: I have a foreach loop but every third time the loop will pass it must do something else. How to do this? Thanks in advance. I tried:

$count = 0
foreach ($cObjects as $oObject) {
   if ($count <= 2) {
     //do things
     $count = 0;
   } else {
     // do other things
   }
   $count++;
}

This didn't work ofcourse, while it resets the count everytime to 0.

Replacing if($count <= 2) to if($count == 2) works.

you have to show your code here – ɹɐqʞɐ zoɹǝɟ Jul 23 '14 at 04:25 — ɹɐqʞɐ zoɹǝɟ, Jul 23 '14 at 04:25
Yes, that's right, `zero` is less an `two`. – brasofilo Jul 23 '14 at 11:43 — brasofilo, Jul 23 '14 at 11:43

The answer from Parixit works only on index array, for collection or associative array you will need a separate $count variable, something like this:

$count = 0
foreach ($cObjects as $oObject) {
   if ($count == 2) {
     //do things
     $count = 0;
   } else {
     // do other things
   }
   $count++;
}

I don't know I understand it proper or not. But you should do something like this

foreach($all as $k=>$single) {
    if($k%3==0) {
        //do every third time
        continue;
    }

    //do something which will not execute every third time
}
