php url queston

the code below sets $number to anyting that is after the/ of of my domain. i wonder how i can make it so that if there is nothing after the / $number automaticlly is set to 1.

$number = basename('http://'.$_SERVER['HTTP_HOST'].($_SERVER['REQUEST_URI'] == '/' ? 1 : $_SERVER['REQUEST_URI']));

 

Try this:

$number = basename($_SERVER['REQUEST_URI'] == '/' ? 1 : $_SERVER['REQUEST_URI']);

PHP:

 

well, that works kinda. what i want is so that if my url is for example http://mydomain.com/2 $number becomes 2 and so on, however if there is nothing behind the / $number becomes 1.

 

It'll try to load a directory if it's a /1 or /2 etc..

You will need some .htaccess to redirect it to a php file to handle it.

 

Yes that is by using rewrite rules in htaccess

 

how would i be using rewrite rules in htaccess to achive this ? i havent used .htaccess very much :/

 

anyone that could help me please ? :/

 

you can used with regular expression , it's simple

 

$number = (is_numeric(basename($_SERVER['REQUEST_URI']))) ? basename($_SERVER['REQUEST_URI']) : 1;

PHP:

 

It goes in your .htaccess file like this:
RewriteEngine ON
RewriteRule ^([0-9]+)$ index.php?number=$1 [L]
