Question

if I have 2 scripts:

includes/ajax_dir/script_1.php

and

includes/script_2.php

From script_1.php I know I can include srcipt_2.php like so:

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

however how could i do this include using an absolute link?…

Answer 1

dirname(__FILE__)."/../" will work great I think.

The reason I use dirname(__FILE__)."/somepath/ everywhere is:

Imagine you have this folder structure

• /
  • index.php
  • /includes
    • /includes/include_libs.php
    • /includes/db.php
• /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 */
