Realtime Template Compressor: Reduces page sizes, loads pages faster, saves bandwidth

This is a port of Logican's Realtime Template Compressor hack from vBulletin 2.2.x to vBulletin 3.5.0 Beta 1. I wrote this by rewriting a version of the original hack, that I wrote for my forums when they ran 3.0.x, so that it would function as a plugin for 3.5.0.

I had originally sent this to Logican for him to release it but he replied granting me permission to release it; hence why I'm releasing this.

Installation is very simple. Just import the plugin via vBulletin's "Download / Upload Plugins" page in the Plugin System in the Admin Control Panel and you're done.

I'll try to correct any bugs that you might find. Let me know if you like this plugin and don't forget to click the install link if you install this.

Update History

Version 1.1.0: The expression was replaced with a more efficient one that increases the compression level from approximately 1-2% to approximately 4-8%.
Version 1.0.0: Initial Release

I just wanted to say I've been using this and it's a great hack.

I'm seeing Output compression saving 3.2% to 15.57%

Excellent work.

[:Judge:]

Well so far so good, I am not getting 20% or even 10% but it seems a little better. Thank You

$pagesaved_byte=$page_byte-$pagenew_byte;
$pagesaved_kilobyte=number_format((($pagesaved_byte)/1024),2);
$pagesaved_perc=number_format(((100*$pagesaved_byte)/$page_byte),2);

and leave only

$page_byte=strlen($output);
$output=preg_replace ('/\r\n(\s*)/', "\r\n", $output);

tested this plugin after removing said variables and code, and still seems to function well

Works for me, thanks!

This Hack causes a Division by Zero PHP Error if a totally blank page is being output (due to missing Template or wrong action for example).
Fixed Code attached.

This looks really usefull knowing that we need to cut down on bandwidth!!
Thanks again ShiningArcanine, KirbyDE and others for working on this.

Does anyone know how (or where) to add the if conditional to show the stats on pages only to admins?

Thanks! A little question though. I've never installed a plugin before, only products. So what do I choose in the "Hook Location
This specifies the location within the vBulletin code of the hook that will fire this plugin function." option field?

Paragraph breaks in text are not showing up
when that text is nested within [ quote ] tags.

I also noticed that when I previewed a post containing other tags (in this case, I had [ size] tags), the paragraph break/space just before the tags disappeared. It doesn't do it if you don't preview the post. So, what happens is that the text shows up okay in the preview, but the space is gone from your actual reply, so when you click on "submit," you don't get the same thing that showed up in preview.
