It is possible, however, to have multiple sets of applications that share a single Code Igniter installation. To do this you will put all of the directories located inside your <kbd>application</kbd> folder into their own sub-folder.</p> <p>For example, let's say you want to create two applications, "foo" and "bar". You will structure your application folder like this: <code>system/application/<var>foo</var>/<br /> system/application/<var>foo</var>/config/<br /> system/application/<var>foo</var>/controllers/<br /> system/application/<var>foo</var>/errors/<br /> system/application/<var>foo</var>/libraries/<br /> system/application/<var>foo</var>/models/<br /> system/application/<var>foo</var>/views/<br /> system/application/<samp>bar</samp>/<br /> system/application/<samp>bar</samp>/config/<br /> system/application/<samp>bar</samp>/controllers/<br /> system/application/<samp>bar</samp>/errors/<br /> system/application/<samp>bar</samp>/libraries/<br /> system/application/<samp>bar</samp>/models/<br /> system/application/<samp>bar</samp>/views/</code> <p>To select a particular application for use requires that you open your main <kbd>index.php</kbd> file and set the <dfn>$application_folder</dfn> variable. For example, to select the "foo" application for use you would do this:</p> <code>$application_folder = "foo";</code> <p>Note: Each of your applications will need its own <dfn>index.php</dfn> file (the index.php file can be named anything you want).</p> </div> <!-- END CONTENT --> <div id="footer"> <p> Previous Topic: <a href="caching.html">Web Page Caching</a> · <a href="#top">Top of Page</a> · <a href="../index.html">User Guide Home</a> · Next Topic: <a href="alternative_php.html">Alternative PHP Syntax</a> <p> <p><a href="http://www.codeigniter.com">Code Igniter</a> · Copyright © 2006 · <a href="http://www.pmachine.com">pMachine, Inc.</a></p> </div> </body> </html>
