How to Parse a Url in PHP

PHP - parse current URL

You can use parse_url();

$url = 'http://www.mydomain.com/abc/';

print_r(parse_url($url));

echo parse_url($url, PHP_URL_PATH);

which would give you

Array
(
    [scheme] => http
    [host] => www.mydomain.com
    [path] => /abc/
)
/abc/

Update: to get current page url and then parse it:

function curPageURL() {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}

print_r(parse_url(curPageURL()));

echo parse_url($url, PHP_URL_PATH);

How do I parse a URL in PHP?

You can use parse_url to get down to the hostname.

e.g.:

var_dump($data);

/*

    [scheme] => http
    [host] => localhost
    [path] => /path/to/
    [query] => here=there
)
*/

PHP: Best way to parse URL query without variable name?

If you are sure that nothing malicious would be passed (or you are just testing), then you could do something like:

$output = eval('return ' . parse_url($_SERVER['REQUEST_URI'])['query'] . ';');

echo $output;

Obligatory notice:

Caution
The eval() language construct is very dangerous because it allows execution of arbitrary PHP code. Its use thus is discouraged. If you have carefully verified that there is no other option than to use this construct, pay special attention not to pass any user provided data into it without properly validating it beforehand.

However, I would advise you use the following method and parse the expression with parser in the linked question:

$exp = parse_url($_SERVER['REQUEST_URI'])['query']; // 1+1
