parse_url — Parse a URL and return its components
$component= -1 ] )
This function parses a URL and returns an associative array containing any of the various components of the URL that are present.
This function is not meant to validate the given URL, it only breaks it up into the above listed parts. Partial URLs are also accepted, parse_url() tries its best to parse them correctly.
The URL to parse. Invalid characters are replaced by _.
On seriously malformed URLs, parse_url() may return

Example #1 A parse_url() example
$url = 'http://username:password@hostname/path?arg=value#anchor';
echo parse_url($url, PHP_URL_PATH);
The above example will output:
Array ( [scheme] => http [host] => hostname [user] => username [pass] => password [path] => /path [query] => arg=value [fragment] => anchor ) /path
This function doesn't work with relative URLs.
This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid.
