Question

尝试创建一个内置于轻量级框架中的简单用户注册表单。然而，当我按下注册时它返回这个：无法连接到mysql因为php_network_getaddresses：getaddrinfo失败：名称或服务未知。当我自己运行代码时，它工作得非常好，但是当我将它埋入我的框架中时它不起作用。我认为这与层次结构有关吗？我不习惯使用包含等，所以也可能是原因。通过index.php？= register

register.inc.php：domain.co.uk/web/includes/register.inc.php

    <?php # register.inc.php

/*

// Redirect if this page was accessed directly:
if (!defined('BASE_URL')) {

    // Need the BASE_URL, defined in the config file:
    require_once ('../includes/config.inc.php');

    // Redirect to the index page:
    $url = BASE_URL . 'index.php';
    header ("Location: $url");
    exit;
