Question

How can i see How many objects of a class are loaded in php. Also do the objects get loaded in a single session on server? Or one can track objects from other sessions also while on the server side?

Actually i am confused. When an object is loaded with the PHP where does it reside? Is it in the browser? Is it in the session and expires as soon as the session expire?

Will this help?

<?php

class Hello {
    public function __construct() {
    }
}

$hello = new Hello;
$hi = new Hello;

$i = 0;

foreach (get_defined_vars() as $key => $value) {
    if (is_object($value) && get_class($value) == 'Hello')
        $i++;
}

echo 'There are ' . $i . ' instances of class Hello';
