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
Specify one of
PHP_URL_FRAGMENT to retrieve just a specific
URL component as a string.
On seriously malformed URLs, parse_url() may return
FALSE and emit a
E_WARNING. Otherwise an associative
array is returned, whose components may be (at least one):
scheme- e.g. http
query- after the question mark
fragment- after the hashmark
If the component parameter is specified a string is returned instead of an array.
$url = 'http://username:password@hostname/path?arg=value#anchor';
echo parse_url($url, PHP_URL_PATH);
The above example will output:
[scheme] => http
[host] => hostname
[user] => username
[pass] => password
[path] => /path
[query] => arg=value
[fragment] => anchor
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 tripple slashes (file:///...) are allowed. For any other scheme this is invalid.
