gopher_parsedir — Translate a gopher formatted directory entry into an associative array.
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.
The directory entry.
Returns an associative array whose components are:
Upon failure, the additional data entry of the returned array will hold the parsed line.
Beispiel #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.
Beispiel #2 Using gopher_parsedir()
<?php
$directory = file("gopher://gopher.example.com");
foreach($directory as $dirent) {
print_r(gopher_parsedir($dirent));
}
?>
