Example#1 Hypothetical output from gopher://gopher.example.com/

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));
}
?>

El resultado del ejemplo seria:
