FDF 函数
Extracts uploaded file embedded in the FDF

fdf_get_attachment

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

fdf_get_attachment — Extracts uploaded file embedded in the FDF

说明

fdf_get_attachment ( resource $fdf_document , string $fieldname , string $savepath ) : array

Extracts a file uploaded by means of the "file selection" field fieldname and stores it under savepath.

参数

fdf_document: The FDF document handle, returned by fdf_create(), fdf_open() or fdf_open_string().
fieldname
savepath: May be the name of a plain file or an existing directory in which the file is to be created under its original name. Any existing file under the same name will be overwritten.

Note:

There seems to be no other way to find out the original filename but to store the file using a directory as savepath and check for the basename it was stored under.

返回值

The returned array contains the following fields:

path - path were the file got stored
size - size of the stored file in bytes
type - mimetype if given in the FDF
