Test code:

    $taran = 0;
    function num($a){
        global $taran;
        $taran++;
        if ($a < 1)
            return;
        else
            num($a - 1);
            num($a - 3);
            return;
    }
    num(5);
    echo($taran);

'; echo($test); echo("

Output:

"); $taran = 0; function num($a){ global $taran; $taran++; if ($a < 1) return; else num($a - 1); num($a - 3); return; } num(5); echo($taran); echo("

More echo()'s for testing

"); echo("

Let's add {} in the if statement as well. They don't affect the code as much as echo()'s.

"); $taranE = 0; echo("Before the function taran is ".$taranE.".
"); function numE($aE){ global $taranE; $taranE++; echo("Inside the function taran is ".$taranE.".
"); if ($aE < 1){ //echo doesn't work here or gives an error echo("
In if a is ".$aE.".
"); return; } else{ num($aE - 1); num($aE - 3); echo("
In else a is ".$aE.".
"); return; } } numE(5); echo("
After the function taran is
"); echo($taranE); ?>
