韩顺平php 利用mysqli实现预编译查询任务（sql语句）

5的用户 id name email
$mysqli=new MYSQLi("localhost","root","hsp123","test");
if(mysqli_connect_error()){
die(mysqli_connect_error());
}
//创建一个预定义的对象?占位符

$sql="select id,name,email from user1 where id>?";
$mysqli_stmt=$mysqli->prepare($sql);
$id=5;
//绑定参数
$mysqli_stmt->blind_param("i",$id);
//绑定结果集
$mysqli_stmt->bind_result($id,$name,$email);
//执行
$mysqli_stmt->execute();
while($mysqli_stmt->fetch()){
 echo "
-----$id--$name---$email";
}

//还想执行另一个sql语句
echo "
***************************";
$id=10;
//绑定参数
$mysqli_stmt->blind_param("i",$id);
//绑定结果集
//$mysqli_stmt->bind_result($id,$name,$email);
//执行
$mysqli_stmt->execute();
while($mysqli_stmt->fetch()){
 echo "
-----$id--$name---$email";
}

//关闭资源
//释放结果
$mysqli_stmt->free-result();
//关闭预编译语句
$mysqli_stmt->close();
//关闭连接
$mysqli->close;
