<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> |
|
