<h3><a class="toc-backref" href="#id2">Anatomy of a Config File</a><a class="headerlink" href="#anatomy-of-a-config-file" title="Permalink to this headline">¶</a></h3>
<p>By default, CodeIgniter has one primary config file, located at
application/config/config.php. If you open the file using your text
editor you&#8217;ll see that config items are stored in an array called
$config.</p>
<p>You can add your own config items to this file, or if you prefer to keep
your configuration items separate (assuming you even need config items),
simply create your own file and save it in config folder.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">If you do create your own config files use the same format as
the primary one, storing your items in an array called $config.
CodeIgniter will intelligently manage these files so there will be no
conflict even though the array has the same name (assuming an array
index is not named the same as another).</p>

<h3><a class="toc-backref" href="#id3">Loading a Config File</a><a class="headerlink" href="#loading-a-config-file" title="Permalink to this headline">¶</a></h3>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">CodeIgniter automatically loads the primary config file
(application/config/config.php), so you will only need to load a config
file if you have created your own.</p>
</div>
<p>There are two ways to load a config file:</p>
<div class="section" id="manual-loading">
<h4><a class="toc-backref" href="#id4">Manual Loading</a><a class="headerlink" href="#manual-loading" title="Permalink to this headline">¶</a></h4>
<p>To load one of your custom config files you will use the following
function within the <a class="reference internal" href="../general/controllers.html"><em>controller</em></a> that
needs it:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;filename&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>Where filename is the name of your config file, without the .php file
extension.</p>
<p>If you need to load multiple config files normally they will be
merged into one master config array. Name collisions can occur,
however, if you have identically named array indexes in different
config files. To avoid collisions you can set the second parameter to
TRUE and each config file will be stored in an array index
corresponding to the name of the config file. Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="c1">// Stored in an array with this prototype: $this-&gt;config[&#39;blog_settings&#39;] = $config</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
</pre></div>
</div>
<p>Please see the section entitled Fetching Config Items below to learn
how to retrieve config items set this way.</p>
<p>The third parameter allows you to suppress errors in the event that a
config file does not exist:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">,</span> <span class="k">FALSE</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
</pre></div>
</div>
</div>
<div class="section" id="auto-loading">
<h4><a class="toc-backref" href="#id5">Auto-loading</a><a class="headerlink" href="#auto-loading" title="Permalink to this headline">¶</a></h4>
<p>If you find that you need a particular config file globally, you can
have it loaded automatically by the system. To do this, open the
<strong>autoload.php</strong> file, located at application/config/autoload.php,
and add your config file as indicated in the file.</p>
</div>
</div>
<div class="section" id="fetching-config-items">
<h3><a class="toc-backref" href="#id6">Fetching Config Items</a><a class="headerlink" href="#fetching-config-items" title="Permalink to this headline">¶</a></h3>
<p>To retrieve an item from your config file, use the following function:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;item_name&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>Where item_name is the $config array index you want to retrieve. For
example, to fetch your language choice you&#8217;ll do this:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$lang</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;language&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>The function returns NULL if the item you are trying to fetch
does not exist.</p>
<p>If you are using the second parameter of the $this-&gt;config-&gt;load
function in order to assign your config items to a specific index you
can retrieve it by specifying the index name in the second parameter of
the $this-&gt;config-&gt;item() function. Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="c1">// Loads a config file named blog_settings.php and assigns it to an index named &quot;blog_settings&quot;</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>

<span class="c1">// Retrieve a config item named site_name contained within the blog_settings array</span>
<span class="nv">$site_name</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;site_name&#39;</span><span class="p">,</span> <span class="s1">&#39;blog_settings&#39;</span><span class="p">);</span>

<span class="c1">// An alternate way to specify the same item:</span>
<span class="nv">$blog_config</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">);</span>
<span class="nv">$site_name</span> <span class="o">=</span> <span class="nv">$blog_config</span><span class="p">[</span><span class="s1">&#39;site_name&#39;</span><span class="p">];</span>

<span id="config-environments"></span><h3><a class="toc-backref" href="#id8">Environments</a><a class="headerlink" href="#environments" title="Permalink to this headline">¶</a></h3>
<p>You may load different configuration files depending on the current
environment. The ENVIRONMENT constant is defined in index.php, and is
described in detail in the <a class="reference internal" href="../general/environments.html"><em>Handling
Environments</em></a> section.</p>
<p>To create an environment-specific configuration file, create or copy a
configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php</p>
<p>For example, to create a production-only config.php, you would:</p>
<ol class="arabic simple">
<li>Create the directory application/config/production/</li>
<li>Copy your existing config.php into the above directory</li>
<li>Edit application/config/production/config.php so it contains your
production settings</li>
</ol>
<p>When you set the ENVIRONMENT constant to &#8216;production&#8217;, the settings for
your new production-only config.php will be loaded.</p>
<p>You can place the following configuration files in environment-specific
folders:</p>
<ul class="simple">
<li>Default CodeIgniter configuration files</li>
<li>Your own custom configuration files</li>
</ul>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">CodeIgniter always loads the global config file first (i.e., the one in application/config/),
then tries to load the configuration files for the current environment.
This means you are not obligated to place <strong>all</strong> of your configuration files in an
environment folder. Only the files that change per environment. Additionally you don&#8217;t
have to copy <strong>all</strong> the config items in the environment config file. Only the config items
that you wish to change for your environment. The config items declared in your environment
folders always overwrite those in your global config files.</p>
