Php5.3 magic method __call and Memory - memory

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.

Answer 1

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.
