您必须将参数绑定到SQL查询，并告诉数据库参数是什么

// prepare sql and bind parameters
$query = "
 INSERT INTO tbl_register 
 (first_name, last_name, email, password, website) 
 VALUES (:first_name, :last_name, :email, :password, :website)
 ";

$statement->bindParam(':last_name', $_POST['last_name']);
$statement->bindParam(':email', $_POST['email']);
$statement->bindParam(':password', $_POST['password']);
$statement->bindParam(':website', $_POST['website']);

 if($statement->execute())
 {
    echo 'Registration Completed Successfully...';

替换这个
