Question

I’m developing a PHP script that loops/iterates more that 10,000 times:

foreach ($array_with_items as $item) {

    // Instantiate the object
    $obj_car = new CarAds($puk, 'ENG', '5');

    $obj_car->detail1 = "Info about detail1";
    $obj_car->detail2 = "Info about detail2";
    $obj_car->detail3 = "Info about detail3";
    $obj_car->detail4 = "Info about detail4";

    // Saves to the database
    $obk_car->save;
}

When I run this code my machine runs out of memory. What can I do to clean the memory in this foreach cycle?

Answer 1

You are instantiating as CarAds objects as your $array_with_items item count. Each one allocate memory.

After the save() method you should deallocate the object with the unset() function:

// Saves to the database
$obj_car->save;

// Unset unneeded object
unset($obj_car);

You can check your memory consumption with the memory_get_usage() (see http://php.net/manual/en/function.memory-get-usage.php)
