(PHP 4, PHP 5, PHP 7)

The function is used for dividing a URL adress into parts which are returned as an associative array.

Parametre

Názov	Dátový typ	Predvolená hodnota	Popis
$url	string		The input URL address to be processed.
$component	int	-1	If the parameter is specified, the function returns only the specified part of the URL address. It can contain the value of one of the following constants: PHP_URL_SCHEME PHP_URL_HOST PHP_URL_PORT PHP_URL_USER PHP_URL_PASS PHP_URL_PATH PHP_URL_QUERY PHP_URL_FRAGMENT See the first example for the description for each part.

Mávratovej hodnoty

Vracia: mixed

Returns false if the URL is malformed.

Returns an associative array with parts of the given URL address. If the URL doesn't contain some part (e.g. the user), the array doesn't contain that key.

If a particular part is specified (by the second parameter), it returns a string with this value (if the port is requested, it returns the int type), or null if the URL doesn't contain that part.

Príklady

An example of URL address parts:

print_r(parse_url('http://john:[email protected]:80/php/basics?view=all&hide=nothing#container'));

If the URL doesn't contain some part (e.g. the user), the array doesn't contain that key.

print_r(parse_url('http://ict.social/php/basics'));

Getting only a defined part of a URL:

<?php
$url = 'http://ict.social:80/php/basics?view=all&hide=nothing#container';

var_dump(parse_url($url, PHP_URL_HOST)); // string
var_dump(parse_url($url, PHP_URL_PORT)); // int
var_dump(parse_url($url, PHP_URL_USER)); // null (URL doesn't contain the user)
