Answer 1

您可能正在使用mysql和mysqli函数。坚持mysqli功能。确保你没有混淆这些功能

Answer 2

使用mysqli

更新连接文件

<html>
<?php


$connection = mysqli_connect("localhost", "root", ""); // Establishing Connection with Server
$db = mysqli_select_db($connection, "test")or die("cannot select DB"); // Selecting Database from Server

?>
</html>

mysqli_query（）需要参数1
