a bit of help please

Hi again. I've been learning php and have done some tutorials. One thing im not sure about and cant find anything on it is, when you look up for example your simple squad site. When you click on a page instead of having /downloads.php or /downloads.htm it has something else. How does that piece of code work ??

Thanks

index.php?view=roster

$view=$_GET['view'];

//View = roster here. So if /path/to/files/content_roster.php exists it will include content_roster.php.

If($view=="") {

include("/path/to/files/content_main.php");

} Elseif(file_exists("/path/to/files/content_".$view.".php)) {

include("/path/to/files/content_".$view.".php);

} Else {

include("/path/to/files/content_main.php");

}

thank you
