从根目录包含文件答案

【问题标题】：Include a file from the root从根目录包含文件
【发布时间】：2016-08-18 03:54:36
【问题描述】：

这是我的应用程序的结构：

core
    application
        controller_base.class.php
        registry.class.php
        router.class.php
        template.class.php
    controller
    include
        config.php
    model
    views
index.php

文件 config.php 包含在 index.php 文件中（这没有问题），这是它包含的内容：

<?php

/*** include the controller class ***/
include(ROOT . '/core/application/controller_base.class.php');

/*** include the registry class ***/
include(ROOT . '/core/application/registry.class.php');

/*** include the router class ***/
include(ROOT . '/core/application/router.class.php');

/*** include the template class ***/
include(ROOT . '/core/application/template.class.php');


/*** autoload model classes ***/
function __autoload($class_name) {
    $filename = strtolower($class_name) . '.class.php';
    $file = ROOT . '/core/model/' . $filename;

    if (!file_exists($file)) {
        return false;
    }

    // include the $class_name class
    include($file);
}

$registry = new registry;

你必须知道常量 ROOT 是这样定义的：

define('ROOT', str_replace('/index.php', '', $_SERVER['SCRIPT_NAME']));

此常量包含值/Lab/Livre/POO/TP1，当然它是应用程序的根。

但是我在 config.php 中包含的所有文件都存在问题。 PHP 向我抛出一个错误，指出在 /Users/tom/www/Lab/Livre/POO/TP1/core/include/config.php 中找不到文件。

所以问题很清楚。我希望 PHP 从应用程序的根目录（index.php 所在的位置）查找文件，但它从 config.php 所在的文件夹中查找。

我有这个问题很长时间了，但我想一劳永逸地找到解决方案。

我不能让它做我想做的事！我希望有人能帮助我。
非常感谢。

P.S.：换句话说，我想使用绝对路径来包含文件。

P.S.：这是完整的错误文本：

【问题讨论】：

你能把完整的错误文本复制给我们吗？
完成！对不起，我忘了。
因此 php 不会尝试将所需的文件加载到与 config.php 相同的文件夹中。它没有找到/Lab/Livre/POO/TP1/core/application/ 中的文件。
你试过dirname(__FILE__) . ROOT . '/core/application/template.class.php'
感谢您的回答！明天我会尝试所有这些，因为它是法国的午夜。

【解决方案1】：

我找到了解决问题的方法。我将 ROOT 常量设置为此：

define('ROOT', $_SERVER['DOCUMENT_ROOT'] . str_replace('/index.php', '', $_SERVER['SCRIPT_NAME']));

但是出了什么问题？
