Question

I need to create something similar to the following within my CodeIgniter project:

• my_config.php
• config_production.php
• config_development.php

Now, my_config.php will be autoloaded. From there, if it is a production server, config_production.php will be loaded; else config_development.php will be loaded.

How should I go about executing this?

I’ve tried doing the following in my_config.php:

<?php
if(gethostbyaddr ("127.0.0.1") == 'hello.sabya'){
    $this->config->load('config_production');
} else {
    $this->config->load('config_development');
}
?>

It is not working as $this->config is not initialized. How can I achieve this?

Answer 1

Two options: You can try referencing the object with $CI instead of $this:

$CI =& get_instance();    //do this only once in this file
$CI->config->load();  
$CI->whatever;

…which is the correct way to reference the CI object from the outside.

Or secondly, you could switch configs from within your config.php file:

<?php
if(gethostbyaddr ("127.0.0.1") == 'hello.sabya'){
    $config['base_url'] = "http://dev.example.com/";
} else {
    $config['base_url'] = "http://prod.example.com/";

}
?>

…etc. Load all the differences between the two if/else blocks.
