Help with PHP

[Dale]

Alright, I don't really know what to call this, so maybe that's why I can't find any tutorials online, but in PHP you know how most sites, atleast professional sites have index.php?id=1 or whatever, with the id, and such. How do I do this? Could someone post code? commented? tutorial? virtually anything is helpful!

Thanks.

Look up $_GET on the PHP Website.

Since this took me a bit to figure out when I started, I'll give a simple example.
This is if you do index.php?page=X

Code Select Expand

<?php         if (isset($_GET['page'] ) )    {        $page = $_GET['page'];    }    else    {        $page = 0;    }         switch ($page )    {                 case 1:                 echo "Contents of index.php?page=1";        break;                 case 2:                 echo "Contents of index.php?page=2";        break;                 default: //OPTIONAL                 echo "Contents of index.php?page=anythingelse";        break;    }?>

Almost, you should cast $_GET['page'] to int before you check it.

Assuming you're expecting an int

Warrior,

When ever you see Something=Value on the URL, this is simply saying $Something = value;

So if I were to have code that said

Code Select Expand


<?
echo("Your name is ".$name);
?>



And you made the URL say, http://yoursite.com/index.php?name=Warrior, you would get a page that says 'Your name is Warrior'.

Hope this helps!

AHAHAHAHA!!!!

CrAzY, Warrior knows more PHP than you could ever hope to.  He was responding to me, because I said cast it to an int.  And he's right.  I use numbers for all of my page traversing, so I'm used to casting to int everything.

ew @ http://site.com/page.php?id=x, or anything similar.
