| Reserved Names |
| ############## |
| |
| 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. |
| |
| Controller names |
| ---------------- |
| |
| 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: |
| |
| - Controller |

| - Default |
| - index |
