What is the best compression using php in terms of speed

I want to use compression so that i can speedup my website.Which is the best compression available? Is compression using ob_start("ob_gzhandler"); the best? Does it compress the images embedded.Is there a way to compress those images?

P.S: I don't have access to the server configuration. I only have a FTP account

Yes, ob_start("ob_gzhandler") is the best you can get if you don't control the server.

The difference between various methods is mainly in efficiency, e.g. some servers or reverse proxies are able to cache compressed data to avoid re-compressing them again. However, gzip is very fast for today's hardware, so even most basic compression in PHP is going to be a net gain.

You should also compress your JS and CSS files, but you shouldn't do that by simply wrapping them in a PHP script, because by default PHP makes files non-cacheable. Any gain from compression will be lost when browsers are forced re-download those files over and over again.

Ideally you should either use a CDN that will compress them for you or ask your host to enable server-level compression for static text files.

No, ob_gzhandler doesn't compress images if you just provide a link in your HTML. Only if you load them into a PHP file as binary data, like with file_get_contents().

I would suggest you use the webserver's functions for that. If you use apache, you can check out http://httpd.apache.org/docs/2.0/mod/mod_deflate.html for instance.
