Hi.

I am new to PHP and notice that on alot of other sites including this one have a ? after the php and then have text afterward. For example I saw a www.mysite.com/index.php?id=202 (that is just an example). If you would change the 202 to say 201 it would show a different page. How do you achieve this. Are they using a template page, and just calling a different document or what?

it is acomplished by using $_GET[]. An example of code that would use this:

PHP Code:


switch($_GET['id']){
     case '1':
           include('1.html');
           break;
     case '2':
           include('2.html');
           break;
     default:
            include('0.html');
} 


If you had this code in your index.php file, you could type in your adress bar: "index.php?id=1" and the page would show the file 1.html

Simply having $_GET['id']; somewheres would work, but it wouldnt show anything different. You have to use if statements, switches etc. to actualy make it useful.


Someone else could probbaly explain it better than I can
