 <?php
 class MyDB extends SQLite3

  function __construct()
  {
     $this->open('Users.db');
  }

  $db = new MyDB();


 $email_address = $_POST['email_address'];
 $password = $_POST['password'];

 $email_address =($email_address);

 $email_address = intval($_POST["email_address"]);
 $password = intval($_POST["password"]);

 password='$password WHERE email_address=? AND where password=?'";


 $stmt = $db->prepare($sql);
 $stmt->bindParam(1, $email_address);
 $stmt->bindParam(2, $password);

 $result = $stmt->execute($sql);

 while($column = $stmt->fetch())
 {
 echo $column["email_address"];
 echo $column["password"];
 };


if($email_address==1){
  echo "<h1>Logged In</h1>";
 }; 

  ?>

错误信息非常简单。在不需要执行方法的情况下，您将为执行方法提供参数。
