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(); ?>
