[PHP] Variables in a config file

[billybombill]

This is an extremely simple tutorial, I'll make one later about how to incorporate databases into this, for now it'll be file-based.

What does this do?

Spoiler

This tutorial will teach you how you can make a configuration file for users to fill information out in. The filled out information can be used easily across the site

Step 1.

Spoiler

Make two files: config.php and index.php

inside of index.php put the following code:

<?php
include('config.php');
?>

<title><?php echo $title; ?> - Index</title>

Welcome to <?php echo $title; ?>! This website was made by <?php echo $name; ?>.

Step 2.

Spoiler

inside of config.php put the following code:

<?php
$title = "Website"; 	/* The name of your website */
$name = "Name"; 		/* Your name */
?>

You can change the variables in config.php to change what is displayed on the site

About the code

Spoiler

First part of the code, the <?php and ?> tags

<?php
PHP CODE
?>

The PHP tags will make the inside code PHP code

----------------------------------------------------------------------------------------------------------------------------------------------------

include('');

include('config.php');

This PHP script will include config.php, letting the webpage with the include code use variables, connections etc from config.php

----------------------------------------------------------------------------------------------------------------------------------------------------

Echos and Variables

<?php echo $variable; ?>

This PHP script will find $variable in the current file or any included files and echo it. Echoing means to display, which you can see using the code.

----------------------------------------------------------------------------------------------------------------------------------------------------

Variables in config.php

<?php
$title = "Website";
$name = "Name";
?>

The above code defines each variable. In this case the code echo $title; would display Website

This is an extremely useful piece of code which can be used to make simple CMS's or websites. Hope this helps anyone, I tried making the tutorial as simple as I could to understand

so you went to the very basics.

 

[billybombill]

so you went to the very basics.

Uhmm yes? Always good to start with basics

Do realize doing that means you'll have to declare them global in any functions to you make.

 

[billybombill]

Yeah, but for a newbie tutorial I think it should be fine

Whoopy doo, you made a tutorial how to use the include() function, great ! Too bad the name of the function is pretty much the tutorial itself.

Seriously, you guys..

Do realize doing that means you'll have to declare them global in any functions to you make.

How would you do it so you don't have to do that, because I always do it this way, and like you've said, I have to declare it as global.

<?php
class test
{
 private $issue, $tissue;
 public function __construct()
 {
   global $config, $db;
 }
}
