php 要開啓上傳功能
修改php.ini

; Whether to allow HTTP file uploads.
file_uploads = On
; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
upload_tmp_dir =e:\temp\temp
; Maximum allowed size for uploaded files.
upload_max_filesize = 2M
E盤temp給users讀取權限，temp/temp給users讀取和寫入的權限。
如果成功temp裏面會寫入臨時的*.tmp文件。
