A useful function in PHP: parse_url

A useful function in PHP, parse_url, is particularly convenient for information capture analysis. For example:
$ 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/
)

Another example:<? PHP
$ URL='Http: // username: password @ Hostname/path? Arg = value # anchor';

Print_r(Parse_url($ URL));

EchoParse_url($ URL,Php_url_path);
?>

output:
array
(
[Scheme] => HTTP
[host] => hostname
[user] => username
[pass] => password
[path] =>/path
[query] => Arg = value
[fragment] => anchor
)
as you can see, each part of a URL can be easily decomposed. It is also easy to obtain the specified part, for example,
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.
