From serverfault Hunt

• If the script is actually running out of memory, you may need to increase PHP's allotted amount. The setting for max memory is in the php.ini file -- look for memory_limit. You'll have to restart apache (or whatever web server you're using).

  Tom O'Connor : Yep. Give it more memory, and maybe try and figure out why your script is so memory-hungry. On the other hand, remember that it's PHP, and it's never gonna be that light on memory usage.
