The return of ini_set(memory_limit..) is the actual memory_limit in use, before changing?

Hi Experts!

I recently obtained that  this could be done to increase memory limit and then return to the original memory_limit

$oldvalue = ini_set('memory_limit','1024M');

ini_set('memory_limit', $oldvalue);

Open in new window

But I couldn't found it in documentation.

Since it could be a very critical operation in the server that uses only 128M,
Could you please confirm?

Thanks in advance!

Here is the man page:

Here is what it says about the return value:
Returns the old value on success, FALSE on failure.

Here is how to test the function:
$oldvalue = ini_set('memory_limit','1024M');
$newvalue =  ini_get('memory_limit');
