gopher_parsedir — Translate a gopher formatted directory entry into an associative array
Description
$dirent
) : arraygopher_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.
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 [port] => 70 ) Array ( [type] => 9 [title] => A picture of my cat. [path] => /pics/cat.png [host] => gopher.example.com [port] => 70 ) Array ( [type] => 1 [title] => A collection of my writings. [path] => /stories [host] => gopher.example.com [port] => 70 ) Array ( [type] => 254 [title] => The HTTP version of this site. [path] => URL:http://www.example.com [host] => gopher.example.com [port] => 70 ) Array ( [type] => 1 [title] => Mirror of this site in Spain. [path] => / [host] => gopher.ejemplo.co.es [port] => 70 ) Array ( [type] => 255 [title] => Welcome to my gopher site. [path] => [host] => error.host [port] => 1 ) Array ( [type] => 255 [title] => Please select one of the options above. [path] => [host] => error.host [port] => 1 ) Array ( [type] => 255 [title] => Send complaints to /dev/null [path] => [host] => error.host [port] => 1 ) Array ( [type] => 255 [title] => Long live gopher! [path] => [host] => error.host [port] => 1 )
