PHP Memory Error(No File Name specified)

I am getting php error like this:

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7077994 bytes) in Unknown on line 0, refer开发者_JAVA百科er:REFERER

I have checked my code there is no infinite loop or code which will take such high memory.

I concern is why it is not showing the error line where it has happened.What is the meaning of Unknown in this case..

Thanks in Advance..

Do you have xdebug installed? I would try to increment memory_limit and profile your script with xdebug. It produces a human-readable text file. So you can read where and how much memory is used.

memory_limit = 128M

increase it in your php.ini file.
