 对苹果信息表做里内容做删除如图1。并且按删除给出一个提示如图2。下图3是点击确定以后的结果
 1 <?php 2 $code = $_GET["code"]; 3 //1.造链接对象 4 $db = new MySQLi("localhost","root","511108","text"); 5 //2.写SQL语句 6 $sql = "delete from fruit where ids='{$code}'";//fruit表格名。ids表格里的主键 7 //3.执行 8 $r = $db->query($sql); 9 if($r)10 {11     header("location:pingguoxinxi.php");//删除完成后，跳转到location:pingguoxinxi.php网页，等于从新刷新    12 }13 else14 {15     echo"删除失败！";    16 }
