Namespace in PHP CodeIgniter Framework

Question

Does CodeIgniter support Namespace?

Answer 1

Just a simple psr-4 autoloading and you are done.

In the config/config.php load composer using

$config['composer_autoload'] = FCPATH.'vendor/autoload.php';

In the root directory run composer install In the generated composer.json add following lines for psr4 autoloading.

    "autoload": {
        "psr-4": {
            "App\\": "application/"
        }
    },  

App would be your namespace in this case.

Example: suppose you have a class Service in libraries folder. You can namespace it with:

Use it in Welcome controller class:
