函數介紹：

函數名作用參數返回值

curl_file_create創建一個 CURLFile 對象, 用與上傳文件。string $filename 必須上傳文件的路徑返回 CURLFile 對象。(https://secure.php.net/manual/en/class.curlfile.php)

string $mimetype 選填文件的Mimetype

string $postname 選填文件名

后記：

關于PHP的文件上傳就完成了，當然這個只是用于學習，實際開發當中，前端一般會使用一些上傳的組件，既美觀又方便。后端一般都是使用別人或者框架封裝好的類。不過學了這些，其實可以自己動手封裝一個文件上傳類了。
