Sometimes we need some custom functionality for our requirement. Let’s see how we can create our own custom library.

Step 1: Create custom library

Create your custom Demo.php in “application/libraries/” folder.

class Demo
{
    private $CI;

    function __construct()
    {
        $this->CI = get_instance();
    }

    function show()
    {
        // Your logic
    }
}

Step 2: Autoload your custom library

Codeigniter libraries are the classes located in system/libraries/ or your application/libraries/ directory.

If you want your libraries to be autoload always, the you can add your custom library in $autoload[‘libraries’] option array.

$autoload['libraries'] = array('demo');

// You can also supply an alternative library name:
// $autoload['libraries'] = array('demo' => 'custom_name');

Step 3: Use your custom library

Now, since your custom library already autoloaded, so now you don’t need to load your custom library in order to use.

// In any controller
$this->demo->show();
