| <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 functions any of these:</p> | |
| <ul> | |
| <li>Controller</li> | |
| <li>CI_Base</li> | |
| <li>_ci_initialize</li> | |
| <li>_ci_scaffolding</li> | |
| </ul> | |
| <p><br /> | |
| If you are running PHP 4 there are some additional reserved names. These ONLY apply if you are running PHP 4.</p> | |
| <ul> | |
| <li>CI_Loader</li> | |
| <li>config</li> | |
