I would add another construct, which will give you more flexibility in the
future:
switch($_GET['pageName']) { //if you're not sure how the variable will pass
use $_REQUEST['pageName']
case '':
//load requested page
break;
case '':
//do something else
break;
default:
//function or load default page
break;
}

Hi there,
I'm gathering from your question you are looking to test the variable
pageName from the url like:
http://www.yoursite.com/index.php?pageName=smoke
and if there is no pageName then set load the default. Personally I would
right it like this.
if(isset($_GET['pageName'])){
// load the requested page
}else{
// load the default page
}
The $_GET variable is a Superglobal that breaks down the request of the GET
(everything after the ? in the URL). If you are unsure if this comes from
the GET method you can also use the superglobal $_REQUEST which is another
array that handles both GET and POST methods.
You check to see if the array element is actually given a value using the
isset() function. If you attempted an is_null() function and there is no
element then PHP will throw a warning.
I hope this helps you on your way.
