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

Popis

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.

Seznam parametrů

dirent: The directory entry.

Návratové hodnoty

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.

Příklad 676. 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.
