GZIP output support on CPanel31 w. PHP

[samsam]

Hi.

Nice to be back on the forums. Hopefully everyone hasn't drifted away...

I have a PHP-based site on cpanel31 that would benefit from gzip output support - ie compressed HTML output.

It has a setting to enable it, so I have, but upon testing it appears as if the output is not actually being compressed.

In exploring the server settings to see what might be the issues here, I had a look at phpinfo for cpanel31.

It reports that Zlib support is there, but that zlib output compression is Off:

ZLib Support enabled
Compiled Version 1.1.4
Linked Version 1.1.4

Directive Local Value Master Value
zlib.output_compression Off Off
zlib.output_compression_level -1 -1
zlib.output_handler no value no value

Now, how can I alter this output compression setting, so that my php app can actually do output compression?

AFAIK, I can't edit php.ini to turn this on, but are there other ways to get this support enabled within PHP?

I know I can make a .htaccess change to enable GZIP output compression using Apache's mod_gzip, which (I think) is available on Dathorn Apache, along the lines of:

mod_gzip_on Yes

But it would be nice to let this be enabled within PHP.

Any advice?

Don't worry about it....

Don't worry about it - it looks as if GZIP support DOES actually work.

One of the sites I was checking it with - the normally excellent:

http://www.websiteoptimization.com/services/analyze/

in-correctly reported GZIP as not enabled.

However a dedicated GZIP reporting site:

http://leknor.com/code/gziped.php

confirmed that GZIP support was there and working fine.

Further scrutiny of the HTTP headers returned by the site also confirms it is working.

NFA required.

mod_gzip in htaccess?

How do we put mod_gzip in htaccess, to speed up the whole site? This code didn't do it.

<IfModule mod_gzip.c>
mod_gzip_on yes
</IfModule>

But this code worked, when I put it in each file:

<?php
ob_start( 'ob_gzhandler' );
?>

Here's the answer to my question. I put these lines in php.ini and now all my pages are gzipped:

zlib.output_compression =ON;
zlib.output_compression_level = 1;

I'm not sure about cpanel31, but I can tell that cpanel17 works fine with this:

<IfModule mod_gzip.c>
mod_gzip_item_include mime ^text/html
mod_gzip_item_include mime ^application/xhtml\+xml
mod_gzip_item_include mime ^text/css
mod_gzip_item_include mime ^text/javascript
</IfModule>

samsam, instead of using some questionable third-parety services to check for GZip output compression you can figure it out yourself from the console:

# wget http://lic40.zaytsev.net/ipb/index.php?showforum=5

P.S. Actually this site is not hosted on the Dathorn's servers.
