 Posted: Wed Jul 26, 2006 8:45 pm Post subject: Gzip Compression Size. |
 |
|
I've searched all over Google for this function or how to do it. All I get are these
tests showing you the uncompressed and compressed percentage of the page. I
want to know what these people use to perform these tests.
How do I get the compressed size of a Gzip page?
How do I get the uncompressed size of a Gzip page?
This will help me display a nice feature on my website on compressed Gzip
pages. I want people to be able to see Gzip in action!
Anyone who know's how to do this, please let me know. Thank You!
Sincerely, TRUSTAbyss |

Unfortunately, I don't think you can get a realtime web browser stat for Gzip bandwidth savings.
The tests done that I've run into on the net show website content that Gzip compresses. They ran this operation independent of a webserver. They just use a program like Winzip that Gzip's the files (that would be none other than Gzip). You could do the test manually and display the savings page by page (compare original with Gzipped version), though.

Uh, download the gzip'ed page then decompress it and compare the sizes.
I think you'll have to write out the HTTP request manually rather than use file_get_contents or something, but other than that it shouldn't be hard.

Download a file with file_get_contents, save to a text file, get the size of the text file, and thats your uncompressed size :-)

You would still need the response headers to know if it was gzip'ed in the first place or not, because as far as I know PHP will automatically decompress it.
Edit: That, or not send a header to say that it accepts gzip compression.

I have found a way to show real-time bandwidth savings by using G-zip. It is an approximation, and needs an external PHP file to do the work. The PHP file is requested. It displays the content (that is sent gzipped) and displays the bandwidth savings at the bottom.
Is anyone interested in this?
