$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。
