PHP的要求在类文件

Question

I have the following folder structure for my site:

    Admin/
    Tech/
index.php
    classes/
    include/
    core/

Everything seems to work except for when i try to call the following code from Admin/index.php

<?php
#including our init.php
require '../core/init.php';
$general->logged_in_protect();
?>

I get the following error for some reason. I can't figure out what to do to fix it or if its even possible to fix.

The core/init.php file has the following code:

<?php
    #starting the users session
    session_start();
    require 'include/database.php';
    require 'classes/users.php';
    require 'classes/general.php';

    $users = new Users($db);
    $general = new General();

    $errors = array();
?>

error that i am receiving:

PHP Warning:  require(include/database.php): failed to open stream: No such file or directory in 

Can someone please help me with this?

Answer 1

You probably just need:

require '../include/database.php';
require '../classes/users.php';
require '../classes/general.php';

But if you use a lot of relative paths, it can get messy real quickly so you might want to consider using your base-directory like for example (you can also use a variable or a constant for that):

require $_SERVER['DOCUMENT_ROOT'] . '/include/database.php';
require $_SERVER['DOCUMENT_ROOT'] . '/classes/users.php';
require $_SERVER['DOCUMENT_ROOT'] . '/classes/general.php';

Answer 2

If you use paths relative to current script location, like this:

<?php

require(dirname(__FILE__).'/../core/other.inc');

...
?>

You always have it under control, regardless of the include_path PHP ini setting.

In your case you should have the following:

<?php
  #including our init.php
  require(dirname(__FILE__).'/core/init.php');
  $general->logged_in_protect();
?>

and core/init.php will look like:

<?php
    #starting the users session
    session_start();
    require(dirname(__FILE__).'/../include/database.php');
    require(dirname(__FILE__).'/../classes/users.php');
    require(dirname(__FILE__).'/../classes/general.php');

    $users = new Users($db);
    $general = new General();

    $errors = array();
?>

Hope this helps.
