(PECL net_gopher >= 0.1)
gopher_parsedir — Translate a gopher formatted directory entry into an associative array.
说明
$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.
参数
-
dirent -
The directory entry.
返回值
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.
范例
Example #1 Hypothetical output from gopher://gopher.example.com/
1 2 3 4 5 6 7 8 9 |
|
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 ));
}
?> 以上例程会输出：
