Hi folks, I'm in need of help with the following situation:

I'm making a php page that retrieves the number typed after my domain from the user and uses it to verify it against a certain variable.

So what I would need would be the number typed in something like the following:

www.mydomain.com/123456

Is there a way to retrieve the typed number? I want the number and the page or folder doesn't exist since it is a variable...

Any help would be greatly appreciated.

Cheers!

$mydomain = "www.mydomain.com/123456";
$pattern = '/\D\d+/';
preg_match($pattern, $mydomain, $matches);
$number = substr($matches[0], 1);
echo $number;

Open in new window

or :
$mydomain = "www.mydomain.com/123456";
$number = explode("/", $mydomain);
echo $number[1];

Open in new window

This would imply that your server has a directory named 123456 and your script would then be the index.html inside that directory:

www.mydomain.com/123456

If you did it this way, your script could find 123456:

www.mydomain.com?123456

I think this would be more complicated than retrieving the value from the string.
Your address may be like www.mydomain.com/123/456/abc/def
how do you want - and what variables - to get them ?

Here's the little function

        function getMyURL(){
            $host = $_SERVER['HTTP_HOST'];
            $self = $_SERVER['PHP_SELF'];
            $par = !empty($_SERVER['QUERY_STRING']) ? $_SERVER['QUERY_STRING'] : null;
            $url = !empty($par) ? "http://$host$self?$par" : "http://$host$self";
            return $url;
        } 

Open in new window


Then you can explode it with "/" and get all variables in an array.

Everything after the host name (and port number if specified) is called the URI.  In PHP you can retrieve the URI using:

 $_SERVER['REQUEST_URI']

In your example  $_SERVER['REQUEST_URI'], would return "/123456".
