Getting whole URL from PHP

[Anon]

Hey,

Is there a way to put the whole URL into a variable in PHP? By this I mean I need to have stuff.mydomain.com put into a variable. The reason I am doing this is because I have a site where a user can type anything.mydomain.com and PHP needs to know what was typed before mydomain.com. I hope that makes sense to everyone...if not then please let me know.

Thanks in advance for the help!

$HTTP_SERVER_VARS["HTTP_HOST"] is the global variable where PHP stores what was typed into the address bar, minus the http:// and anything after the end of the domain.

Then you can just use the explode() function to get the various parts of the request.

Kevin,

You could also use the parse_url() function instead of explode(). The advantage is the function will spilt your URL into an array with the following elements: scheme, host, port, user, pass, path, query, and fragment. These elements coorespond to the URL as follows:

scheme://user:pass@host:port/path?query#fragment

More info can be found in the manual at:

HTH!!
