gopher_parsedir

Description

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.

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 dl("gopher.so"); $directory = file("gopher://gopher.example.com"); foreach($directory as $dirent) {     print_r(gopher_parsedir($dirent)); } /* Expected 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 ) */ ?>
