parse_url
Parse a URL and return its components
(PHP 4, PHP 5)
mixed 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
- url
The URL to parse
- component
Specify one of
PHP_URL_SCHEME,PHP_URL_HOST,PHP_URL_PORT,PHP_URL_USER,PHP_URL_PASS,PHP_URL_PATH,PHP_URL_QUERYorPHP_URL_FRAGMENTto 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):
-
scheme- e.g. http -
host -
port -
user -
pass -
path -
query- after the question mark? -
fragment- after the hashmark#
If the component parameter is specified a string is returned instead of an array.
Examples
Example 2572. 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
Notes
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.
