title: Codeigniter - make own constant instead of using config/constant.php
body: <p>Is there any possibility we can make our own <code>constants</code> and does the work instead of using <code>constants.php</code> in <code>config</code> folder? Cause I wanted to create some <code>constants</code> and my <code>constants.php</code> is too long, is there any possibility I can make a <code>custom_constants.php</code>?</p>
