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:

$ Dirs = '. /'; // specify if (is_dir ($ dirs) {$ hanld = opendir ($ dirs); while ($ file = readdir ($ hanld ))! = False) {echo "file name:". $ file. "<br/>" ;}closedir ($ hanld) ;}else {echo 'is not a directory ';}

Output result:
File Name:
File Name: B
File Name: www.manongjc.com

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.
