<h1>Running Multiple Applications with one Code Igniter Installation</h1>

<p>By default it is assumed that you only intend to use Code Igniter to manage one application, which you will build in your
<dfn>system/application/</dfn> directory.  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>
