PHP Functions in detail: Parse_url ()

The Parse_url () function resolves the URL and returns its constituent parts. Its usage is as follows: Array parse_url (string URL) This function returns an associative array containing the various components of an existing URL. If one of these is missing, an array entry is not created for this component. The components are: scheme– such as HTTP Host Port User Pass Path query– in question marks? After fragment– after the hash symbol # This function does not imply that the given URL is legal, it simply separates the parts of the list above. Parse_url () can accept an incomplete URL and try to parse it correctly. This function has no effect on the URL of the relative path. $url = "http://www.nowamagic.net/welcome/"; $parts = Parse_url ($url); Print_r ($parts); ?> Copy Code The results of the program run as follows: Array ([scheme] + http [host] = www.nowamagic.net [path] =/welcome/) $url = ' Http://username:password@hostname/path?arg=value#anchor '; Print_r (Parse_url ($url)); Echo Parse_url ($url, Php_url_path); ?> Copy Code Program output: Array ( [Scheme] = http [Host] = hostname [User] = Username [Pass] = password [Path] =/path [Query] = Arg=value [Fragment] = Anchor ) /path Copy Code As you can see, it's easy to break out the various parts of a URL, which is easy if you want to take the specified part out, such as: Echo Parse_url ($url, Php_url_path); Copy Code 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
