Detecting URL problems

[phpnewbie1]

Sory if my english is bad.

My applications have search engine friendly urls. I want to have diferent banners for all category.
Its not posible with applications.

I want to write the code:

When php detect url: "http://mysite.com/category1/" then display banners for that category.
when detect url: "http://mysite.com/category2/" then display banners for that category.

I think this maybe done with IF. ELSE statement???

Some like this:

IF url = "http://mysite.com/category1/" {
show baner page 1

IF url = "http://mysite.com/category2/" {
show banner page 2

Its that posible?

Can anyone help me to write this code?

This 5 minutes job, but I not known to write it :-(

Thanks anyway.

this might be what you're looking for:
[code]
<?

$uri = $_SERVER['REQUEST_URI'];
$elements = explode("/", $uri);

// see whats in it
print_r($elements);

// use it
if($elements[1]=="category1")
{
  print "you are in category1";
}
if($elements[1]=="category2")
{
  print "you are in category2";
}

?>
[/code]
