php parse_url function tutorial ​

parse_url
(PHP 4, PHP 5)

parse_url - Parses a URL and returns its component parts

Description
mix parse_url (string $url[summary$part=-1])
This function parses a URL and returns an associative array containing any of the individual components of the URL that also exist.

This function is not meant to validate a given URL, it only breaks the above part of it. Partial URLs are also accepted, and parse_url() will try to parse them correctly.

Parameters

URL
URL parsing. Invalid characters replaced _.


Part
Specifying a 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 retrieves just the components of a specific URL as a string.


Return value
For severely malformed URLs, parse_url() may return FALSE and issue E_WARNING. Otherwise an associative array is returned, whose components may be (at least one):

Plan - e.g. URL
Master
Port
User
Pass
Path
Query - question mark after?
snippet-post-hashmark #

If some parameters are specified return a string instead of an array.

Modify

Release Notes
5.1.2 Time component parameters


Example

$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
