Php tutorial opendir function and opendir syntax

Opendir syntax
Opendir (path, context) Directory
Function Description
Open the directory handle. If the opendir () function opens a directory handle, the function returns a directory stream; otherwise, false is returned.
 
Let's take a look at opendir to list all file instances in the directory.
*/

$ Dirs = './'; // specifies the current time
If (is_dir ($ dirs ))
{
$ Hanld = opendir ($ dirs );
 
While ($ file = readdir ($ hanld ))! = False)
{
Echo "file name:". $ file. "<br/> ";
}
Closedir ($ hanld );
}
Else
{
Echo 'not a directory ';
}

/*
Output result
File Name:
File Name: B
File Name: www. bKjia. c0m
*/

Tips and comments
Note: Starting from PHP 5.0.0, the path parameter supports ftp: // URL wrapper.

Note: in PHP 4.3.0, the path parameter can be any URL that supports the directory list, but in PHP 4, only file: // URL wrapper supports this function.
