Zend zip class -- files are too big for php to handle

[ivai]

I'm trying to use the zend zip class to create zip files dynamically for users to download multiple files, and several of the files exceed 50mb (making for a cd-sized zip file, around 500mb). If I try the app with small files, it works a-okay, but when i try with the actual files, php dies and says that I attempted to allocate too much memory. Is there any way to circumvent this?

Things I really really don't want to do:
1.) Increase the max file size in php.ini
2.) Call the zip command directly from php

I can't think of a solution to this... any help would be greatly appreciated

Hi,

the manual contains a section about the most important configuration directives and where you can set them:

memory_limit: PHP_INI_ALL

You should be able to increase the limit in the script itself.

Add e.g.
ini_set("memory_limit", 550000000);

on top of the script. But that can be dangerous because with a 500mb file PHP would use 500mb of memory. The server must have sufficient memory resources. In worst case the web server (or even the complete OS) could crash if your scripts uses too much memory.

How does the script look like ?
