Hello everybody,

I am trying to learn php. but i don't understand one thing. why this type of link mean:

http://www.webmaster-talk.com/usercp.php?
http://www.webmaster-talk.com/member.php?&u=13247


if anybody help me and tell me in details then that will be very helpful for me.

The question mark allows data to be passed to that php file.

http://www.webmaster-talk.com/usercp.php?:

This will do nothing as there is no data after the '?', but it is there for future url's where there would be data to pass.

http://www.webmaster-talk.com/member.php?&u=13247

This one holds the data '13247' as 'u'. Within the member.php file, there will be code that looks for any data defined as 'u' and if found it will then perform a different function from normal.

So, we could have the following in member.php:

PHP Code:

$user = $_GET['u'];

if ($user == '13247')

     { $rank = 'member'; }

else
     { $rank = 'guest'; } 


Hope this helps,

Steve.
