最后的返回值是一个集对象，为了方便清晰的看到结果 我们用到了fetch_all(),fetch_row(); fetch_object();
//造连接对象$db = new MySQLi("localhost","root","12345678","heiheihei");//准备SQL语句$sql = "insert into cou values('3-111','嘿嘿','803')"; //执行SQL语句$r = $db ->query($sql);if($r)//如果$r是ture{ echo "执行成功";
}else { echo "执行失败";
}
<?php//造连接对象$db = new MySQLi("localhost","root","12345678","heiheihei");//准备SQL语句$sql = "update cou set cname='哈哈' where tno='803'"; //执行SQL语句$r = $db ->query($sql);if($r)
{ echo "执行成功";
}else { echo "执行失败";
}?>
<?php//造连接对象$db = new MySQLi("localhost","root","12345678","heiheihei");//准备SQL语句$sql = "delete from cou where tno='803'"; //执行SQL语句$r = $db ->query($sql);if($r)
{ echo "执行成功";
}else { echo "执行失败";
