PHP?id=

I was wondering if anyone could tell me the PHP Code for getting the IDs at the end of page, ex.
http://www.website.com/index.php?id=01
One of my friends gave me this code:

Code:

<html>

<?php
if (strpos($_POST['id'],'01') !== FALSE) {
?>

... HTML CODE HERE ...

<?php
} if (strpos($_POST['id'],'02') !== FALSE) {
?>

... HTML CODE HERE ...

<?php
} if (strpos($_POST['id'],'03') !== FALSE) {
?>

... HTML CODE HERE ...

<?php
}
?>

</html>

But when i tried using it, the IDs didn't work. I changed all of the FALSEs to TRUE and then it just displayed all of them. Every time i tested it the ID part of it had no effect, except for when it caused an error. Thx to whoever can tell me

EDIT: I gave a completely wrong answer...

Just use $_GET instead of $_POST

Um, I have no idea what that code is trying to do. :shock:

Why dont you try this way, eh?

Code:

<?php

$id = $_GET['id'];

// Then from here on, you can set what to
// do based on the value of the "id" variable

if($id=="1")
{
     echo "Number 1? No way!";
}
elseif($id=="2")
{
     echo "Number 2. Not bad I guess.";
}
else
{
     echo "You're ID number is not cool enough to be in my presence. Be gone!";
}

?>

I agree with Dan, much cleaner this way. I assume you want to include() a different page depending on the variable?

Yeah...i posted on a PHP forum and some guy with 4000 posts or something just said to use get instead of post and it worked great.

Oh I'm sorry, you want the GET variable so it would be $_GET, not $_POST. My bad.

Or you could just use $_REQUEST, that would work for both get and post variables.
