how to declare all your includes in one file that will be loaded in all project in PHP

Question

i'm working on a project but, i'm sick of loading all the libraries in every single page

my project directories are something like this

|---x (( PHP PAGES ))
  |--- x1.php (( PHP FILE ))
  |--- x2.php (( PHP FILE ))
|---y (( PHP PAGES ))
  |--- y1.php (( PHP FILE ))
  |--- y2.php (( PHP FILE ))
|---includes (( LIBRARIES ))
a.php (( PHP FILE ))
b.php (( PHP FILE ))
c.php (( PHP FILE ))

i tried to load all my libraries in a single file and load that file in all pages, but the problem comes up from the directories like for example loading libraries in x1.php will be something like this "../include/", but loading in a.php just needs "include/" i know there is a way to reach the "includes" directory no matter from where the request comes from but i have no clue how to do this.

Thanks

Loading each and every single file as an include will add unwanted bloat and possibly slow down your site. What you might try is class autoloading: http://www.php.net/manual/en/language.oop5.autoload.php

It eliminates the need to scatter includes all over the place but only the files you really need will be included.

thanks a lot. if i use this in functions.php that will be in includes/functions.php should i load my libraries like "/includes" or "../includes" ?? that's still depending on the requesting script right ? – trrrrrrm Feb 10 '10 at 06:47
Even the most experienced php programmers get confused on whether to use './filename' or '../filename' specially when two files might have a common include. The best way to overcome this is to put your stuff in directory that is on the include path - or to change the include path to point to the directory where the files are. you might also consider using include_once() or require_once() instead of include() or require() – e4c5 Feb 11 '10 at 03:13

The answer to your question is to set an include_path. By default, PHP looks for included files in the same directory as the calling file, but if you set an include_path it'll look there instead.

However, class autoloading and the __autoload() function are even better in the long run, so go with e4c5's answer.

Check this library: https://github.com/FrederickMontiel/SimpleRouter-php

include_once __DIR__."/vendor/autoload.php";

use EasyProjects\SimpleRouter\Router as Router;

$router = new Router();
/*
    Require all files from folder to final subfolder
    
    Then if you have:
    app
        controllers
            - UsersController.php
            Implicits
                - UserImplicit.php
        models
            - UsersModel.php
        roots
            - UsersRoot.php
    
    Require all files php from controllers, implicits, models and roots
*/
$router->importAll("./app");

/*
    Require all files from folder
    
    If you have:
    app
        controllers
            - UsersController.php
            Implicits
                - UserImplicit.php
        models
            - UsersModel.php
        roots
            - UsersRoot.php
        - home.php
    
    Require all files php in app, only home.php
*/
$router->import("./configs");
