## Description

string filetype ( string filename)

Returns the type of the file. Possible values are fifo, char, dir, block, link, file, and unknown.

Returns `FALSE` if an error occurs. filetype() will also produce an `E_NOTICE` message if the stat call fails or if the file type is unknown.

> 心得:As of PHP 5.0.0 this function can also be used with some URL wrappers. Refer to 附錄 L for a listing of which wrappers support stat() family of functionality.
