Question

I have a script with using a lot of Magic method __call.
The script have 15 000 iterance and the object is bigger.
After every iterance the memory grows. I use unset or $val = null; but the memory continues to grow.

What can i do?

An Exemple :

$data = null;
foreach ($field['method']['actions'] as $action) {
    // si l'action ne concerne pas le name space principal
    if (!array_key_exists('get', $action)) {
        continue;
    }
    if (array_key_exists('begin', $action)) {
        $data .= $action['begin'];
    }
    if (array_key_exists('action', $action)) {
        $obj = $notice->__call('get' . ucfirst($action['action']));
        $notice->clear();
        if (is_object($obj)) {
            $rsl = $obj->__call('get' . ucfirst($action['get']));
            $obj->clear();
            echo "\n" . 'get' . ucfirst($action['get']) . ' : '  . number_format(memory_get_usage());
            $data .= $rsl;
            unset($rsl);
        } else {
            $data .='';
        }
        $obj = null;
    } else {
        $data .= $notice->__call('get' . ucfirst($action['get']));
        $notice->clear();
        echo "\n" . 'get' . ucfirst($action['get']) . ' : '  . number_format(memory_get_usage());
    }
    if (array_key_exists('end', $action)) {
        $data .= $action['end'];
    }
}
//--
class Notice{
    //--

    protected $instanceObj = null;

    public function __call($name, $arguments = null) {
        $this->instanceObj = $this->$name($arguments);
        return $this->instanceObj;
    }

    public function clear(){
         $this->instanceObj = null;
     }

    //--
}

An exemple of log file :

getField : 24,446,752
getField : 24,447,352
getField : 24,447,720
getField : 24,448,096
getField : 24,483,320
getField : 24,483,336
getField : 24,483,728
...
getField : 25,267,936
...
getField : 35,596,712
...

You can see the memory never stop to brows.

The only solution is to sequence the script several execution. The problem is not PHP Symfony but generates too many objects. So I run the script Pacquet x. Otherwise it led to a saturation of memory.
