PHP文件包含在目录中的绝对链接

Question

，如果我有2个脚本：

includes/ajax_dir/script_1.php 

和

includes/script_2.php 

从script_1.php我知道我可以包括srcipt_2.php像这样：

include("../script_2.php"); 

然而，我怎么能做到这一点，包括使用绝对链接？...

Answer 1

dirname(__FILE__)."/../"将工作的伟大，我认为。

我用dirname(__FILE__)."/somepath/之所以处处是：

想象一下，你有这样的文件夹结构

• /
  • 的index.php
  • /包括
    • /包括/ include_libs。 PHP
    • /inclu DES/db.php中
• /AJAX
  • dostuff.php

//index.php 
<?php 
include("includes/include_libs.php"); 


// /includes/include_libs.php 
<?php 
include("includes/db.php"); //here is the problematical part 

// /ajax/dostuff.php 
<?php 
include("../includes/include_libs.php"); /** 
    this will cause that include_libs tries to include /ajax/includes/db.php instead of /includes/db.php, to fix this trouble, change the problematical line in includes_libs.php to 

    include(dirname(__FILE__)."/db.php"); 

which will ensure that real db.php will be called */ 

Answer 2

喜欢的东西：

include(realpath(dirname(__FILE__)."../script_2.php"));
