This is wholly incorrect. This method will compress your code, not cached in any way, every time a page is executed, output buffering the entire thing.

Lets go over the process so we understand.

- The output buffer begins storing output.
- Your sites code executes.
— Anything your code would “echo” to the user is sent to the output buffer instead
- Your code completes
- the output buffer containing the full content of your site is gziped
— Gzip cannot execute on a partial document and must execute on the full completed html document
- the final gzip result is sent to the user, once all PHP has completed

Therefore the end user will not receive nor have displayed a single line of HTML until they receive the entire compressed document, at which point it can be uncompressed.
This can actually create the impression that the page is loading slower because the browser will normally begin to render content as PHP flushes pieces of HTML out to the user, whereas now the user will receive it all at once, after PHP is entirely done.

I have found in my testing on Oasisband.net that PHPs delay compressing my HTML is greater than the delay of the user downloading it uncompressed when on a relatively fast connection.

Lastly ob_gz_handler to my understanding is more or less deprecated for Zlib Output Compression.

An internal server error has occured!
Please try again later.

Can anybody help me wats the right way to do this.

I added to a client site and everything was fine and noticeably sped up, however, the application within a sub folder displayed ascii “nonsense” – like if you were to open say a SWF file in word or notepad!

Anyone know why this would be and how to overcome it?

Also i use wpmu, do i need to add the header code to all templates?
Thank you very much

Thanks!

output_handler = ob_gzhandler;

That’s it.

Also, compressing in a PHP file, the:

ob_end_flush();

line is not necessary for it to function properly. PHP will flush it automatically. To simplify, all you need is:

ob_start(‘ob_gzhandler’);

At the top of a PHP file. You could also prepend a php file to other php files using htaccess. But if you could do that, you might as well use the htaccess example given in this post.

will the above .htaccess code(php_value output_handler ob_gzhandler) also compress the Javascript / CSS files too?

thanks,

Since I have access to .htaccess, can I also compress the .css files via .htaccess?

Thanks once again

Thanks for the code :)

My entire site is PHP based. Thanks… :D

<?php ob_start (“ob_gzhandler”);
header(“Content-type: text/css; charset: UTF-8″);
?>

I’ll play around with it when I go upstairs, where everything I have that has my website is. Right now I just used Notepad really quickly to create it and uploaded it through my host’s file uploader.
