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.

Answer 1

I have find the solution in these link:

Thanks for all your advices!

Answer 2

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.

Answer 3

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.

Answer 4

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.
