PHP help

[Spectrum]

Hi, can anybody help me? I was fiddling with my site's layout a while ago, didn't change anything important, and then, my PHP code stopped working.

<?php
if ($id == $null) include("home.php");
else include("$id.php");
?>

Does anybody know why? It's the exact same code I've always used...

You sure your host still supports it? O.o

I dun see anything wrong with it...

 

[pokejungle]

did you accidently delete any files?

do any of your new files contain an ext different from .php...I dunno either...

<?php
if ($id == [b]null[/b])
     include("home.php");
else
     include("$id.php");
?>

Unless, you have a previously declared variable, $null, initiated to null ($null=null;), then that wouldn't work. I don't even think that you could name a variable $null in PHP, since it's a predefined keyword.

Edit: PHP should behave the same way as Java and C++ with the null keyword. You just need to enter "null", since it's not a variable.

I hope you a 404 page script on your site in case someone tries to enter a bad value for $id. Your script doesn't have a failsafe if block.

It's also considered better form to oraganise the code as I did (above).

Yeah, I try to keep my site as organised as possible. And yes my host supports it, all pages on my site are linked by index.php?id=... and when you click the links they show up... I'll try what Hades said, thanks.
