How to destruct an object in symfony 1.4?

Question

Possible Duplicate:
php/symfony/doctrine memory leak?

I need to know if there is a way to destroy an object in symfony 1.4, because I have a cicle for that insert on database.

foreach ($array_data as $payroll_employee)
{
  $discounts = new PayrollDiscounts();
  $discounts->setPayrollId($payroll_id);
  $discounts->save();
  $discounts->free(TRUE);
  unset($discounts);
}

and display this Error:

Fatal error: Allowed memory size of 134217728 bytes exhausted

So I need to know a way to deliver memory.

Note that this is really a Doctrine (or Propel maybe?) issue rather than Symfony, I've added a tag. — John Carter, Nov 27 '12 at 19:48
How many items do you have in `$array_data` ? By the way, you should try every update from this answer: http://stackoverflow.com/a/4066680/569101 — j0k, Nov 27 '12 at 21:10

I've found it can be tricky to get Symfony to free memory, though you might try setting $discounts = null; instead of unsetting it (see What's better at freeing memory with PHP: unset() or $var = null).

For simple bulk inserts like that I'd suggest doing the inserts with SQL (preferably PDO) instead of Doctrine.

Using unset() will specifically free the memory associated with the variable, however I doubt that the setting of the $discounts variable is where you are running into your memory allocation issue, as it would have been overwritten with each pass of the loop. Is $array_data itself too large? Is one of the methods executed on the $discounts object causing the problem?

Try to set some breakpoints in your code to better find where the memory problem is being encountered.

You can destroy an object in PHP using unset(). That's what you are doing already.

In order to increase the memory available - you have to set the PHP config value

memory_limit

to a larger number.

increasing memory_limit is only a stop-gap solution. – John Carter Nov 27 '12 at 19:45
Fair enough. But in my limited experience this is the only feasible way when there is a ORM in play. – madflow Nov 27 '12 at 19:50
