You can use a site to view http headers such as http://web-sniffer.net/

Some sites will return the PHP version in the server section of the header for example here's a response from a site I just tested:

Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8e-fips-rhel5 
mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.12


This is more likely to work on sites hosted on a standard shared hosting platform such as cPanel.

Finding out which version PHP a remote server is running
I'm making a little animation with some gears. I want that if I rotate the first gear, all the gears rotate with the gain given by the gears.

For doing that I've choose the copy rotation constraint. But in my case, sometime a gear turn one time and the second turn tiwce. With the copy roation I can only put an influence between 0 and 1. 

So my question is : Is there a way to put a copy rotation constraint with an influence higher than 1? Or is there an other solution to do what I want?
