Have a look at parse_url.

$url = parse_url('http://domain.com/1/index.php');

EDIT: Take a look at $_SERVER['REQUEST_URI'], to get the current URL. Use that instead of $url['path'].

Then you can split $url['path'] on /, and get the 1st element.

// use trim to remove the starting slash in 'path'
$path = explode('/', trim($url['path'], '/')); 

$id = $path[0]; // 1

$url should be retrieved from adress bar,other part working fine

gen_Eric Over a year ago

@PankajjKumar: Try $_SERVER['PATH_INFO'] instead of $url['path']. If that doesn't work var_dump($_SERVER), one of the values will have the path ('/1/index.php').

$_SERVER['PATH_INFO'] returns nothing

gen_Eric Over a year ago

@PankajjKumar: Try $_SERVER["REQUEST_URI"] (or $_SERVER["SCRIPT_NAME"], or $_SERVER["PHP_SELF"]) instead. Use var_dump($_SERVER), to see what values there are, I forget which one is the one you need.

@PankajjKumar: What returns nothing? What code is on that page?

Given the information provided, this will do what you ask... it's not what I would call a robust solution:

$url = $_SERVER['PATH_INFO']; // e.g.: "http://domain.com/1/index.php";
$pieces = explode("/", $url);
$num = $pieces[3];

$url = "domain.com".$_SERVER["REQUEST_URI"]; $pieces = explode("/", $url); $num = $pieces[3]; echo $num;

split the server path by forward slashes (explode('/', $_SERVER['REQUEST_PATH']);)
remove empty entry from the beginning
take the first element
make sure it is an integer (intval(), or a simple (int) cast).

No need to use regular expressions for this.

You use preg_match() to match the domain and get the 1st segment.

$domain = http://www.domain.com/1/test.html

preg_match("/http:\/\/.*\/(.*)\/.*/", "http://www.domain.com/1/test.html");

echo $matches[1];  // returns the number 1 in this example.
