# gopher_parsedir

(PECL)

gopher_parsedir -- Translate a gopher formatted directory entry into an associative array.

## Descrição

array gopher_parsedir ( string dirent )

gopher_parsedir() parses a gopher formatted directory entry into an associative array.

While gopher returns `text/plain` documents for actual document requests. A request to a directory (such as /) will return specially encoded series of lines with each line being one directory entry or information line.

## Parâmetros

`dirent`

  The directory entry.

## Valores de retornado

Returns an associative array whose components are:

- `type` - One of the `GOPHER_XXX` constants.

- `title` - The name of the resource.

- `path` - The path of the resource.

- `host` - The domain name of the host that has this document (or directory).

- `port` - The port at which to connect on `host`.

Upon failure, the additional `data` entry of the returned array will hold the parsed line.

## Exemplos

Exemplo 1. Hypothetical output from `gopher://gopher.example.com/`
    0All about my gopher site.	/allabout.txt	gopher.example.com	70
    9A picture of my cat.	/pics/cat.png	gopher.example.com	70
    1A collection of my writings.	/stories	gopher.example.com	70
    hThe HTTP version of this site.	URL:http://www.example.com	gopher.example.com	70
    1Mirror of this site in Spain.	/	gopher.ejemplo.co.es	70
    iWelcome to my gopher site.		error.host	1
    iPlease select one of the options above		error.host	1
    iSend complaints to /dev/null		error.host	1
    iLong live gopher!		error.host	1

In the example above, the root directory at gopher.example.com knows about one `DOCUMENT` identified by `0` located at `gopher://gopher.example.com:70/allabout.txt`. It also knows about two other directory (which have their own listing files) at `gopher://gopher.exmaple.com:70/stories` and at `gopher://gopher.ejemplo.co.es:70/`. In addition there is a binary file, a link to an HTTP url, and several informative lines.

By passing each line of the directory listing into gopher_parsedir(), an associative array is formed containing a parsed out version of the data.

Exemplo 2. Using gopher_parsedir()
`<?php $directory = file("gopher://gopher.example.com"); foreach($directory as $dirent) { print_r(gopher_parsedir($dirent)); } ?>`
