Performance issue of Zip Class

[eluser]stanleyxu[/eluser]
I have found another issue related to Zip class: When creating a Zip file, this class will cache the zip content in memory, which means double memory usage.

Code:

$this->zipfile = $data.$dir."\x50\x4b\x05\x06\x00\x00\x00\x00"

When a script tries to make a big zipfile, it might be failed. Because usually PHP server allows 16M memory usage for each script execution. I have modified the source again (download) and implement it in another way. I think it really make sense. ^^)

Furthermore, Zip->archive($filepath) can be extended to Zip->archive($filepath, $volume=16384)....
