# parse_url

(PHP 3, PHP 4, PHP 5)

parse_url -- Parse a URL and return its components

## Description

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_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):

- `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.

## ChangeLog

Version | Description
--- | ---
5.1.2 | Added the component parameter

## 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

## Notes

> Note: 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.
