# parse_url

(PHP 3, PHP 4, PHP 5)

parse_url -- Parse a URL and return its components

## Descrizione

array parse_url ( string url )

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.

## Elenco dei parametri

- `scheme` - e.g. http

- `host`

- `port`

- `user`

- `pass`

- `path`

- `query` - after the question mark ?

- `fragment` - after the hashmark #
