PHP包含文件。显示未找到错误文件 [英] PHP include file. Showing error file not found

问题描述

我使用的是include函数，它给出了错误。那是找不到的文件。
在根目录中我有 - index.php和config.php

I am using include function and it is giving errors. That is file not found. In the root directory I have - index.php and config.php

index.php 包括 config.php 并有一些其他数据。

index.php includes config.php and has some other data.

config.php 包含数据库详细信息并包含function / function.php

config.php has database details and includes function/function.php

有一个文件夹用户，它在 calculate.php 中有一个文件 calculate.php
我已经包含了AJAX功能并在AJAX调用中加载一个文件。文件 cal2.php ，位于用户文件夹中。
现在， cal2.php 具有 config.php 的包含功能，例如：

There is a folder user and it has a file calculate.php in calculate.php I have included AJAX functionality and a file is loaded in it on AJAX call. File is cal2.php and it is located in user folder. Now this, cal2.php has a include function for config.php like:

包括../ config.php;

include "../config.php";

当 cal2.php 从 calculate.php加载

function / function.php 文件未加载。它显示找不到 function / function.php的文件

function/function.php file is not loaded. It shows file not found for function/function.php

因此，文件结构为：

• root


• /index.php


• /config.php


• /user/calculate.php


• /user/cal2.php


• /function/function.php

• root
• /index.php
• /config.php
• /user/calculate.php
• /user/cal2.php
• /function/function.php

如何继续，没有function.php包含cal2.php的错误

How to proceed and not have function.php include error for cal2.php

推荐答案

您应该更改config.php以使用functions.php的绝对路径。如果你有PHP 5.3或更高版本，那就这样做：

You should change config.php to use an absolute path to functions.php. If you have PHP 5.3 or greater, do it like this:

include(__DIR__.'/functions/functions.php');

如果您仍在使用PHP 5.2（或者，上帝禁止，之前的某些内容），您可以这样做这样：

If you are still using PHP 5.2 (or, god forbid, something earlier), you can do it this way:

$dir = dirname(__FILE__);
include($dir.'/functions/functions.php');

__FILE__魔术常量始终包含当前PHP文件名的值，因此 dirname（__ FILE __） call将为您提供当前脚本的完整文件系统路径。

The __FILE__ magic constant always contains the value of the current PHP file name, so the dirname(__FILE__) call will give you the full filesystem path of the current script.
