parse_url (PHP 3, PHP 4, PHP 5) parse_url -- Parse a URL and return its components Descriptionmixed parse_url ( string url [, int component] )
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.
Parameters
- component
Specify one of 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 to retrieve just a specific
URL component as a string.
Return Values
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):
If the component parameter is specified a
string is returned instead of an array.
Examples
Example 1. A parse_url() example <?php
$url = 'http://username:password@hostname/path?arg=value#anchor';
print_r(parse_url($url));
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 |
|
NotesNote:
This function doesn't work with relative URLs.
Note:
parse_url() 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.
