# gopher_parsedir

(PECL net_gopher >= 0.1)

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

### Description

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.

### Parameters

`dirent`

  The directory entry.

### Return Values

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.

### Examples

Example #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.

Example #2 Using gopher_parsedir()

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

The above example will output:

    Array (
      [type] => 0
      [title] => All about my gopher site.
      [path] => /allabout.txt
      [host] => gopher.example.com
