		#获取后缀，转换成小写

		#4 mime

		$finfo=new Finfo(FILEINFO_MIME_TYPE);#使用php方法检测mime

		$mime_type=$finfo->file($file['tmp_name']);

			return false;

		}

		

		#5 永久化保存  move_uploaded_file!!!!

		

		#要保存的地方

		#创建时间子目录

		$subdir=date('YmdH').'/';

		if(!is_dir($subdir)){

			mkdir($subdir);

		}

		#科学起名 uniqid

		$upload_filename=uniqid('cc_',true).$ext;

		}else{

#测试

$a=new upload();

var_dump($a->uploadone($_FILES['logo']));
