On the fly "if" conditions deciding factor?

[ubh]

Horrible thread title, but again would know how to word it... moving on.

Is there something in PHP that would allow me to be a bit more divers about a if condition and its deciding factor on the fly?

For instance I want to do a security check and make sure that anyone who has not be set with a authorized SESSION username will be redirected if the variable "pageName" equals any of the following. Something like this maybe?

if(!isset($_SESSION['username']) && $pageName=="this"||"that"||"theOther"||"anythingElse")
{
   header('Location: [url]http://www.website.com/home.php');[/url]
} 

Thanks for your time.

This part won't work: $pageName=="this"||"that"||"theOther"||"anythingElse", but otherwise you're good to go. I'd put those into an array, and make it simple:

$aPages = array(
    'this',
    'that',
    'theOther',
    'anythingElse',
);
if(!isset($_SESSION['username']) && in_array($pageName, $aPages))
{
    header....
} 

There is no rule that says you need to compare a variable to a constant, it is legal to do $this == $that.

Interesting. Thanks Fou-Lu, again

Np.
I should mention that I lied in my above post. $this is reserved for objects of course, so you can't use it as a variable: $that == $other

lol.. I did notice that, but I thought I would be reading to much into it. Comparing via $pageName, $aPages and the array was the light bulb I was looking for
