This article analyzes the usage of the opendir function in php. Share it with you for your reference. The details are as follows:

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. The Code is as follows:

The Code is as follows:

$ Dirs = './'; // specifies the current time
If (is_dir ($ dirs ))
{
$ Hanld = opendir ($ dirs );

While ($ file = readdir ($ hanld ))! = False)
{
Echo "file name:". $ file ."
";
}
Closedir ($ hanld );
}
Else
{
Echo 'not a directory ';
}

Output result:
File Name:
File Name: B
File Name:

Tips and notes:

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.
