58<h1>Reserved Names</h1>
59
60<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>
61<h3>Controller names</h3>
62<p>Since your controller classes will extend the main application controller you
63must be careful not to name your functions identically to the ones used by that class, otherwise your local functions
64will override them. The following
Derek Allard13fbacd2010-07-05 07:31:17 -0400[diff] [blame]65is a list of reserved names. Do not name your controller any of these:</p>
