<p>The Language Class provides functions to retrieve language files and
|
|||
|
lines of text for purposes of internationalization.</p>
|
|||
|
<p>In your CodeIgniter <strong>system</strong> folder, you will find a <strong>language</strong> sub-directory
|
|||
|
containing a set of language files for the <strong>english</strong> idiom.
|
|||
|
The files in this directory (<strong>system/language/english/</strong>) define the regular messages,
|
|||
|
error messages, and other generally output terms or expressions, for the different parts
|
|||
|
of the CodeIgniter framework.</p>
|
|||
|
<p>You can create or incorporate your own language files, as needed, in order to provide
|
|||
|
application-specific error and other messages, or to provide translations of the core
|
|||
|
messages into other languages. These translations or additional messages would go inside
|
|||
|
your <strong>application/language/</strong> directory, with separate sub-directories for each idiom
|
|||
|
(for instance, ‘french’ or ‘german’).</p>
|
|||
|
<p>The CodeIgniter framework comes with a set of language files for the “english” idiom.
|
|||
|
Additional approved translations for different idioms may be found in the
|
|||
|
<a class="reference external" href="https://github.com/bcit-ci/codeigniter3-translations">CodeIgniter 3 Translations repositories</a>.
|
|||
|
Each repository deals with a single idiom.</p>
|
|||
|
<p>When CodeIgniter loads language files, it will load the one in <strong>system/language/</strong>
|
|||
|
first and will then look for an override in your <strong>application/language/</strong> directory.</p>
|
|||

<div class="admonition note">

<p>If you want to support multiple languages in your application, you would provide folders inside

any additional ones needed by your application.</p>

<p>The Language class in CodeIgniter is meant to provide an easy and lightweight

way to support multiplelanguages in your application. It is not meant to be a

full implementation of what is commonly called <a class="reference external" href="http://en.wikipedia.org/wiki/Internationalization_and_localization">internationalization and localization</a>.</p>
|

<p>We use the term “idiom” to refer to a language using its common name,
|
|||
|
rather than using any of the international standards, such as “en”, “en-US”,

|
or “en-CA-x-ca” for English and some of its variants.</p>

<p>Language files must be named with <strong>_lang.php</strong> as the filename extension.
|

|
For example, let’s say you want to create a file containing error messages.
|
|||
|
You might name it: error_lang.php</p>
|
|||
|
<p>Within the file you will assign each line of text to an array called

|
<code class="docutils literal"><span class="pre">$lang</span></code> with this prototype:</p>

<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$lang</span><span class="p">[</span><span class="s1">'language_key'</span><span class="p">]</span> <span class="o">=</span> <span class="s1">'The actual message to be shown'</span><span class="p">;</span>

<p>In order to fetch a line from a particular file you must load the file

<p>Where filename is the name of the file you wish to load (without the

file extension), and language is the language set containing it (ie,

|
english). If the second parameter is missing, the default language set
|
|||
|
in your <strong>application/config/config.php</strong> file will be used.</p>
