Reading File Directories : Useful functionsTo get this script going, we need to use some key functions off php.net.
is_dir(PHP 3, PHP 4 )
is_dir -- Tells whether the filename is a directory Descriptionbool is_dir ( string filename)Returns TRUE if the filename exists and is a directory. If filename is a relative filename, it will be checked relative to the current working directory.
opendir(PHP 3, PHP 4 )
opendir -- open directory handle Descriptionresource opendir ( string path)Returns a directory handle to be used in subsequent closedir(), readdir(), and rewinddir() calls. If path is not a valid directory or the directory can not be opened due to permission restrictions or filesystem errors, opendir() returns FALSE and generates a PHP error. You can suppress the error output of opendir() by prepending `@' to the front of the function name.
readdir(PHP 3, PHP 4 )
readdir -- read entry from directory handle Descriptionstring readdir ( resource dir_handle)Returns the filename of the next file from the directory. The filenames are returned in the order in which they are stored by the filesystem.
closedir(PHP 3, PHP 4 )
closedir -- close directory handle Descriptionvoid closedir ( resource dir_handle)Closes the directory stream indicated by dir_handle. The stream must have previously been opened by opendir(). Good code practice to close an opened file stream.
