If PHP is configured correctly, you can use a local PHP.INI file to over-ride values. Just create in the directory where the script is:
Code:
[php]
memory_limit = 64M ; Maximum amount of memory a script may consume (8MB)
You might even submit a ticket to support concerning this to see if they can put in a copy of the server's PHP.INI in your local directory with the above modification.. or just change the value for the server itself.
