Correct, garbage collector was added to PHP 5.3, prior to 5.3 PHP did only reference counting. PHP 5.3 was released in June of 2009.
Here is a series of articles that describes it in detail
https://www.php.net/manual/en/features.gc.php
Especially look at this example where the same script is executed with and without GC

I don't even think most mainstream uses of PHP have done the process-per-request model for decades, but I could be wrong.
