提交表单的处理文件 doAction3.php

<?php/** * Created by PhpStorm. * User: DreamBoy * Date: 2016/4/8 * Time: 20:29 */header('content-type:text/html;charset=utf-8');include_once 'upload.func.php';$fileInfo = $_FILES['myFile'];//$file = uploadFile($fileInfo);//$file = uploadFile($fileInfo, 'MyFiles');$allowExt = array('jpeg', 'jpg', 'png', 'gif', 'html', 'txt');$file = uploadFile($fileInfo, 'MyFiles', false, $allowExt);print_r($file);
