本文实例讲述了php实现基于PDO的预处理。分享给大家供大家参考,具体如下:
$servername="localhost"; $username="root"; $password="admin"; //$dbname为我的test数据库 $dbname="test"; try{ $conn=new PDO("mysql:host=$servername;dbname=$dbname",$username,$password); //设置pdo错误异常处理 $conn->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); //预处理SQL并绑定参数 $stmt=$conn->prepare("INSERT INTO user(user_first,user_last,age)VALUES(:user_first,:user_last,:age)"); $stmt->bindParam(":user_first",$user_first); $stmt->bindParam(":user_last", $user_last); $stmt->bindParam(":age",$age); //要执行的插入记录 $user_first="xiao"; $user_last="liang"; $age=15; $stmt->execute(); //要执行的插入记录 $user_first="xiao"; $user_last="cheng"; $age=23; $stmt->execute(); echo "News record created successfully!"; }catch(PDOException $e){ echo "Error:".$e->getMessage(); } $conn=null;
希望本文所述对大家PHP程序设计有所帮助。
