1、<form enctype="multipart/form-data">
2、<form enctype="multipart/form-data">
3、<input type="file" name="upload_pic[]" multiple>
4、$upload->upload(array($_FILES['upload_pic'])); 或 $upload->upload($_FILES); 否则会出现“非法上传对象”
5、上传配置 $config=array('saveName' => array('uniqid','')); 否则会引起重名覆盖
6.可以选择把上传数组转换为单个文件状态，然后进行单个判断上传
