Implimenting gzip compression in a webpage

[jordanwb]

How would I go about implementing gzip compression in my PHP scripts?

 

Also do I need to compile PHP with any particular USE flags on my Gentoo install?

See output buffering functions

[jordanwb]

So I'd put this before any output:

 

ob_start("ob_gzhandler");

 

What about after I ouput stuff? Do I call

 

ob_end_flush();

 

I remember from MyBB that there was an option to control how hard the compressor should try. Also what about cookies?

[Mchl]

There's also zlib.output_compression which lets you set compression level.

Cookies will be in the header, so output compression shouldn't affect them.

 

Why not have compression done automatically if you're building your own version of PHP

The thing is I don't want to be always compressed. I'm designing my Site Content Manager to support Plugins. There will be a compression plugin featuring a compression algorithm. Also the compression amount will be on a per user basis. If one wants high compression, then higher compression will be attempted.

 

I checked make.conf and PHP was compiled with zlip support.

ini_set may work here, I'm not entirely sure. You should check it out

I found this: http://www.desilva.biz/php/zlib.html

I have used Devin Doucette's Archive class before and found that it worked really well. You can  <a href="http://www.phpclasses.org/browse/package/945.html">get it here</a>.

This class isn't exactly what jordanwb is looking for. It allows creating end decompressing zip/tar/gzip archives, while jordanwb wants to compress web pages as they're sent from server to browser.

Precisely.
