| <h1>Reserved Names</h1> |
| |
| <p>In order to help out, CodeIgniter uses a series of functions and names in its operation. Because of this, some names cannot be used by a developer. Following is a list of reserved names that cannot be used.</p> |
| <h3>Controller names</h3> |
| <p>Since your controller classes will extend the main application controller you |
| must be careful not to name your functions identically to the ones used by that class, otherwise your local functions |
| will override them. The following |
| is a list of reserved names. Do not name your controller any of these:</p> |
| <ul> |
| <li>Controller</li> |
| <li>CI_Base</li> |
| <li>_ci_initialize</li> |
| <li>Default</li> |
| <li>index</li> |
| </ul> |
| <h3>Functions</h3> |
| <ul> |
| <li>is_really_writable()</li> |
| <li>load_class()</li> |
| <li>get_config()</li> |
| <li>config_item()</li> |
| <li>show_error()</li> |
| <li>show_404()</li> |
| <li>log_message()</li> |
| <li>_exception_handler()</li> |
| <li>get_instance()</li> |
| </ul> |
| <h3>Variables</h3> |
| <ul> |
| <li>$config</li> |
| <li>$mimes</li> |
| <li>$lang</li> |
| </ul> |
| <h3>Constants</h3> |
