<h1>Managing your Applications</h1>
60
<p>By default it is assumed that you only intend to use CodeIgniter to manage one application, which you will build in your
61
<dfn>application/</dfn> directory. It is possible, however, to have multiple sets of applications that share a single
62
CodeIgniter installation, or even to rename or relocate your <dfn>application</dfn> folder.</p>
64
<h2>Renaming the Application Folder</h2>
66
<p>If you would like to rename your <dfn>application</dfn> folder you may do so as long as you open your main <kbd>index.php</kbd>
67
file and set its name using the <samp>$application_folder</samp> variable:</p>
69
<code>$application_folder = "application";</code>
71
<h2>Relocating your Application Folder</h2>
73
<p>It is possible to move your <dfn>application</dfn> folder to a different location on your server than your <kbd>system</kbd> folder.
74
To do so open your main <kbd>index.php</kbd> and set a <em>full server path</em> in the <samp>$application_folder</samp> variable.</p>
77
<code>$application_folder = "/Path/to/your/application";</code>
80
<h2>Running Multiple Applications with one CodeIgniter Installation</h2>
82
<p>If you would like to share a common CodeIgniter installation to manage several different applications simply
83
put all of the directories located inside your <kbd>application</kbd> folder into their
86
<p>For example, let's say you want to create two applications, "foo" and "bar". You could structure your
87
application folders like this:</p>
89
<code>applications/<var>foo</var>/<br />
90
applications/<var>foo</var>/config/<br />
91
applications/<var>foo</var>/controllers/<br />
92
applications/<var>foo</var>/errors/<br />
93
applications/<var>foo</var>/libraries/<br />
94
applications/<var>foo</var>/models/<br />
95
applications/<var>foo</var>/views/<br />
96
applications/<samp>bar</samp>/<br />
97
applications/<samp>bar</samp>/config/<br />
98
applications/<samp>bar</samp>/controllers/<br />
99
applications/<samp>bar</samp>/errors/<br />
100
applications/<samp>bar</samp>/libraries/<br />
101
applications/<samp>bar</samp>/models/<br />
102
applications/<samp>bar</samp>/views/</code>
105
<p>To select a particular application for use requires that you open your main <kbd>index.php</kbd> file and set the <dfn>$application_folder</dfn>
106
variable. For example, to select the "foo" application for use you would do this:</p>
108
<code>$application_folder = "applications/foo";</code>
110
<p class="important"><strong>Note:</strong> Each of your applications will need its own <dfn>index.php</dfn> file which
111
calls the desired application. The index.php file can be named anything you want.</p>
