调用：

$Uploads = new UploadsController();
$file_path = $Uploads->uploadsiImgMobile($v['pic_front'][$kn]),  

文件操作方法：

 $new_purchase_file= str_replace('/tmp/','/files/',$request->purchase_file);
 //如果没有文件夹 则自动创建
 //$_SERVER['DOCUMENT_ROOT'] 表示从根目录/开始
 $nowDay = date('Y-m-d');
 if(!is_dir($_SERVER['DOCUMENT_ROOT'].'/uploads/files/'.$nowDay)){
    
    
       mkdir($_SERVER['DOCUMENT_ROOT'].'/uploads/files/'.$nowDay,0777,true);//创建年+月的文件夹权限为最高
 }

copy($_SERVER['DOCUMENT_ROOT'].$request->purchase_file, $_SERVER['DOCUMENT_ROOT'].$new_purchase_file);
unlink($_SERVER['DOCUMENT_ROOT'].$request->purchase_file); //删除tmp目录下的文件


$new_path = '/uploads/images/'.$nowDay.'/'.$newName;

rename($old_path,$_SERVER['DOCUMENT_ROOT'].$new_path);

$new_purchase = str_replace('/tmp/','/images/',$pictures_file);//图片路径
