How to get current recursion level in a PHP function

Question

How to get current recursion level in a PHP function ? I mean, is there any \"magical\" (or eventually normal) function like this :

function doSomething($thi         


        

Answer 1

    function doSomething($things) {
static $level = 0;
    if (is_array($things)) {
        foreach ($things as $thing) {
$level++;
            doSomething($thing);
        }
    } else {
        // This is what I want :
        echo $level
    }
}
