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 _.
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
(except when
PHP_URL_PORT is given, in which case the return
value will be an integer).
On seriously malformed URLs, parse_url() may return
FALSE.
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
| Version | Description |
|---|---|
| 5.4.7 | Fixed host recognition when scheme is omitted and a leading component separator is present. |
| 5.3.3 |
Removed the E_WARNING that was emitted when URL
parsing failed.
|
| 5.1.2 | Added the component parameter. |
Note:
This function doesn't work with relative URLs.
Note:
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.
