How to get each part of php URL (global variables)

$url = "http://www.electrictoolbox.com/php-extract-domain-from-full-url/";
$parts = parse_url($url);

Output: Array ( [scheme] => http [host] => www.electrictoolbox.com [path] => /php-extract-domain-from-full-url/ )

Example 2:

$url = 'http://username:password@hostname/path?arg=value#anchor';
print_r(parse_url($url));
echo parse_url($url , PHP_URL_PATH);
?>

output: Array ( [scheme] => http [host] => hostname [user] => username [pass] => password [path] => /path [query] => arg=value [fragment] => anchor )

It is easy to decompose the various parts of a URL, and it is also easy to extract the specified parts: echo parse_url($url, PHP_URL_PATH); In the second parameter, set the following parameters: PHP_URL_SCHEME, PHP_URL_HOST, PHP_URL_PORT, PHP_URL_USER, PHP_URL_PASS, PHP_URL_PATH, PHP_URL_QUERY or PHP_URL_FRAGMENT.
