<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>
