About gzip

Hello,
I need to compressed my website's code because Its taking so much time for uploading so I want to know about the gzip.
Anybody can help me how I can implement gzip for my website.

Thanks in advance

You should edit (or create) .htaccess file in your root directory with following content:

# BEGIN GZIP
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</ifmodule>
# END GZIP

Code (markup):

Also this should be helpful:

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/html "access 8 hours"
ExpiresByType text/css "access 8 hours"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 7 days"
</IfModule>

Hello NT,
Thank you very much for your suggestion.I am waiting for another answer after that I will choose you as a best answer......

 

The above is great for static files, but it does jack for your PHP -- since you posted this in PHP, I figure that's what you're asking about; gzipping your code output?

Before you output ANYTHING from your PHP, do this:

if (strpos($_SERVER['HTTP_ACCEPT_ENCODING'],'x-gzip')!==false) {
	$compressionType='x-gzip';
	ob_start();
} else if (strpos($_SERVER['HTTP_ACCEPT_ENCODING'],'gzip')!==false) {
	$compressionType='gzip';
	ob_start();
} else $compressionType = '';

Code (markup):

... and before you exit, you'll want to do this:

if ($compressionType) {
	if (ob_get_length() < 2048) {
		/* don't waste time compressing anything less than 2k */
		ob_end_flush();
	} else {
		$contents=ob_get_contents();
		ob_end_clean();
		header('Content-Encoding: '.$compressionType);
		print("\x1F\x8B\x08\x00\x00\x00\x00\x00");
		$contents=gzcompress($contents,$data->settings['compressionLevel']);
		/* strip off faulty 4 digit CRC when printing */
		print(substr($contents,0,strlen($contents)-4));
	}
}

Code (markup):

... and that's how you compress the PHP output. Mind you if you're already playing games with the outputbuffer you really can't do this. I actually put these in my template_header and template_footer functions since in my code the templates are the only thing allowed to output... uhm... anything.
