It's a $_GET variable. Disadvantages? It's shown in the URL, which means that it's not exactly acceptable for passwords etc. It also can't handle as much text as $_POST can. Advantages? It makes dynamic pages pretty easy to whip up in comparison to $_POST variables. Allows for users to visit the page without having to POST to it. Allows bookmarking etc.

you can get val from $_post!you  can use post when you want to post big val!

disadvantages are hackers trying to input code

you would need something like this to avoid that

 

the call: whatevevername.php?id=1

 

the receiving code

 

if(isset($_GET['id'))

{

$id=htmlspecialchars($_GET['id'];

}

 

that messes up a hack attempt instead of just trying to bring the data into a variable that could be executed for example if you echoed echo "$id";

 

if there was a hack in there you would be executing the code

 

i do that with post too
