How to track PHP errors?

Question

I get the following error:

[23-Feb-2011 19:51:29] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 512 bytes) in /obj/class.db.php on line 60

My problem is that I do not know where this error is. Line 60 of the .db.php class is one of the most used functions in my application (Database Read () function).

How can I track where this error came from?

Answer 1

You can try using http://www.xdebug.org/

Answer 2

Most likely, exactly where the problem arose - your script absorbs almost all the limitations of 128 megabytes, and then the database class tries to allocate a little more space for reading something from the database, and the script barfs crosses the limit.

What are you doing, why do you need to use 128 megapixel memory?

Answer 3
