php - 将 mysql 的 php 代码转换为 sqlite 时出现问题

Question

我正在将 MySQL 的 php 代码转换为 SQLite。我是 SQLite 新手。请帮我转换这部分。

if (mysqli_fetch_row($result)== NULL){               
                 echo "Inserting new record <br />";
                 $stmt = mysqli_prepare($con,"INSERT INTO received_queries VALUES (?,?,?,?)");
                 mysqli_stmt_bind_param($stmt,'sssi', $qid, $sender_screen_name, $text,$val);
                 mysqli_stmt_execute($stmt);
                 mysqli_stmt_close($stmt);  
                 }

当你使用PDO时，你可以使用这样的东西:

if (!$result->fetch (PDO::FETCH_NUM))
{
   echo 'Inserting new record <br/>';
   $statement = $database->prepare ('INSERT INTO received_queries VALUES (?, ? ,? ,?)');
   $statement->execute (array ($qid, $sender_screen_name, $text, $val));
}
