Debug PHP memory leak. Tracking Link Counter?

Question

I have a pretty big php script that skips memory. I was able to figure out which object was leaking, but I was not able to figure out where the script was located, it was leaking. My part of the script contains a reference to a leaking object.

Is there a way to track (and preferably backtrace) where / when the PHP object has a reference count increased or decreased?

Answer 1

You can use profiling tools to find out what memory leak I prefer http://xdebug.org/ and http://code.google.com/p/webgrind

Answer 2

Try using:

• http://www.php-debug.com
• http://php.net/manual/en/function.debug-backtrace.php
• http://xdebug.org/docs/execution_trace

In addition, I suggest writing code in a simple way for debugging and separating debugging procedures from code.
