<h1>Managing your Applications<a class="headerlink" href="#managing-your-applications" title="Permalink to this headline">¶</a></h1>
<p>By default it is assumed that you only intend to use CodeIgniter to
manage one application, which you will build in your <em>application/</em>
directory. It is possible, however, to have multiple sets of
applications that share a single CodeIgniter installation, or even to
rename or relocate your application directory.</p>
<div class="section" id="renaming-the-application-directory">
<h2>Renaming the Application Directory<a class="headerlink" href="#renaming-the-application-directory" title="Permalink to this headline">¶</a></h2>
<p>If you would like to rename your application directory you may do so
as long as you open your main index.php file and set its name using
the <code class="docutils literal"><span class="pre">$application_folder</span></code> variable:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$application_folder</span> <span class="o">=</span> <span class="s1">&#39;application&#39;</span><span class="p">;</span>

</div>
<div class="section" id="relocating-your-application-directory">
<h2>Relocating your Application Directory<a class="headerlink" href="#relocating-your-application-directory" title="Permalink to this headline">¶</a></h2>
<p>It is possible to move your application directory to a different
location on your server than your web root. To do so open
your main index.php and set a <em>full server path</em> in the
<code class="docutils literal"><span class="pre">$application_folder</span></code> variable:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$application_folder</span> <span class="o">=</span> <span class="s1">&#39;/path/to/your/application&#39;</span><span class="p">;</span>

<h2>Running Multiple Applications with one CodeIgniter Installation<a class="headerlink" href="#running-multiple-applications-with-one-codeigniter-installation" title="Permalink to this headline">¶</a></h2>
<p>If you would like to share a common CodeIgniter installation to manage
several different applications simply put all of the directories located
inside your application directory into their own sub-directory.</p>
<p>For example, let’s say you want to create two applications, named “foo”
and “bar”. You could structure your application directories like this:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">applications</span><span class="o">/</span><span class="nx">foo</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">foo</span><span class="o">/</span><span class="nx">config</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">foo</span><span class="o">/</span><span class="nx">controllers</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">foo</span><span class="o">/</span><span class="nx">libraries</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">foo</span><span class="o">/</span><span class="nx">models</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">foo</span><span class="o">/</span><span class="nx">views</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">bar</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">bar</span><span class="o">/</span><span class="nx">config</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">bar</span><span class="o">/</span><span class="nx">controllers</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">bar</span><span class="o">/</span><span class="nx">libraries</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">bar</span><span class="o">/</span><span class="nx">models</span><span class="o">/</span>
<span class="nx">applications</span><span class="o">/</span><span class="nx">bar</span><span class="o">/</span><span class="nx">views</span><span class="o">/</span>
</pre></div>
</div>
<p>To select a particular application for use requires that you open your
main index.php file and set the <code class="docutils literal"><span class="pre">$application_folder</span></code> variable. For
example, to select the “foo” application for use you would do this:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$application_folder</span> <span class="o">=</span> <span class="s1">&#39;applications/foo&#39;</span><span class="p">;</span>
</pre></div>
</div>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">Each of your applications will need its own index.php file
which calls the desired application. The index.php file can be named
anything you want.</p>
