PHP zip using pack()

[helpmeinphp]

Hi,

I have read these articles on how to zip using the pack function:
http://www.zend.com/zend/spotlight/c...zip-files1.php
http://www.weberdev.com/get_example-4066.html

These articles show how to zip files.
But not how to read them. Also is it possible to gzip using pack().

Is there a more complete library on zip and gzip using pack() (Not the PEAR lib)

Thanks

Hello,

At www.phpclasses.org there's a more complete class: http://www.phpclasses.org/browse/file/3191.html

But unfortunately, there's no method included to extract zip-files.

I've written a ZIP-class to create ZIP-files, and I managed to write a method to read a ZIP-file, and almost extract it.
There's still one problem: when creating a ZIP-file, we remove the first two bytes of the encoded string (using gzipcompress). The first two bytes are always the same. Then we remove the last four bytes, that's the CRC.
The problem is, I can't recalculate the CRC, and we need to append the CRC to the encoded string again to let gzuncompress decompress it.
If someone has a solution to that, my extract method works.
