$servername="localhost";

$username="root";

$password="admin";

//$dbname为我的test<a href="/database/database.html" target="_blank">数据库</a>

$dbname="test";

try{

  $conn=newPDO("mysql:host=$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!";

}<a href="/tags.php/catch/" target="_blank">catch</a>(PDOException$e){

  echo"Error:".$e->getMessage();

}

$conn=null;
