预编译执行 dml 语句

query("set names gbk");
	
	$sql = "insert into user1(name,psw,email,age) values(?,?,?,?)";
	
	$mysqli_stmt = $mysqli->prepare($sql);
	
	//绑定参数
	
	$name = "公子玮";
	$psw = "123";
	$email = "gonziwei.sohu,com";
	$age = 24;

	$mysqli_stmt->bind_param("sssi",$name,$psw,$email,$age);
	
	$b = $mysqli_stmt->execute();
	
	if(!$b){
		die("failed".$mysqli_stmt->error);
		exit();
	}else{
		echo "success
"; } //继续添加 $name = "编程大师"; $psw = "123"; $email = "dashi.sohu,com"; $age = 25; $mysqli_stmt->bind_param("sssi",$name,$psw,$email,$age); $b = $mysqli_stmt->execute(); if(!$b){ die("failed".$mysqli_stmt->error); exit(); }else{ echo "success
"; } //继续添加 $name = "编程屌丝"; $psw = "123"; $email = "diaoshi.sohu,com"; $age = 25; $mysqli_stmt->bind_param("sssi",$name,$psw,$email,$age); $b = $mysqli_stmt->execute(); if(!$b){ die("failed".$mysqli_stmt->error); exit(); }else{ echo "success
"; } $mysqli->close(); ?>

预编译执行 dql 语句:

connect_error){
		die($mysqli->connect_error);
		exit();
	}
	//create a predefined object and get a position
	
	$sql = "select id,name,email from user1 where id > ?";
	
	$mysqli_stmt = $mysqli->prepare($sql);
	$id = 5;
	//bind param
	$mysqli_stmt->bind_param("i",$id);
	
	//bind results
	
	$mysqli_stmt->bind_result($id,$name,$email);
	
	
	$mysqli_stmt->execute();
	
	while ($mysqli_stmt->fetch()){
		echo "--$id--$name--$email
"; } $mysqli_stmt->close(); $mysqli->close(); ?>
