427<p>The Language Class provides functions to retrieve language files and
428lines of text for purposes of internationalization.</p>
429<p>In your CodeIgniter <strong>system</strong> folder, you will find a <strong>language</strong> sub-directory
430containing a set of language files for the <strong>english</strong> idiom.
431The files in this directory (<strong>system/language/english/</strong>) define the regular messages,
432error messages, and other generally output terms or expressions, for the different parts
433of the CodeIgniter framework.</p>
434<p>You can create or incorporate your own language files, as needed, in order to provide
435application-specific error and other messages, or to provide translations of the core
436messages into other languages. These translations or additional messages would go inside
437your <strong>application/language/</strong> directory, with separate sub-directories for each idiom
438(for instance, ‘french’ or ‘german’).</p>
439<p>The CodeIgniter framework comes with a set of language files for the “english” idiom.
440Additional approved translations for different idioms may be found in the
441<a class="reference external" href="https://github.com/bcit-ci/codeigniter3-translations">CodeIgniter 3 Translations repositories</a>.
442Each repository deals with a single idiom.</p>
443<p>When CodeIgniter loads language files, it will load the one in <strong>system/language/</strong>
444first and will then look for an override in your <strong>application/language/</strong> directory.</p>
445<div class="admonition note">
446<p class="first admonition-title">Note</p>
447<p class="last">Each language should be stored in its own folder. For example,
448the English files are located at: system/language/english</p>

473<p>If you want to support multiple languages in your application, you would provide folders inside
474your <strong>application/language/</strong> directory for each of them, and you would specify the default
475language in your <strong>application/config/config.php</strong>.</p>
476<p>The <strong>application/language/english/</strong> directory would contain any additional language files
477needed by your application, for instance for error messages.</p>
478<p>Each of the other idiom-specific directories would contain the core language files that you
479obtained from the translations repositories, or that you translated yourself, as well as
480any additional ones needed by your application.</p>
481<p>You would store the language you are currently using, for instance in a session variable.</p>

516<p>The Language class in CodeIgniter is meant to provide an easy and lightweight
517way to support multiplelanguages in your application. It is not meant to be a
518full implementation of what is commonly called <a class="reference external" href="http://en.wikipedia.org/wiki/Internationalization_and_localization">internationalization and localization</a>.</p>
519<p>We use the term “idiom” to refer to a language using its common name,
520rather than using any of the international standards, such as “en”, “en-US”,
521or “en-CA-x-ca” for English and some of its variants.</p>

554<p>In order to fetch a line from a particular file you must load the file
555first. Loading a language file is done with the following code:</p>
556<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">lang</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;filename&#39;</span><span class="p">,</span> <span class="s1">&#39;language&#39;</span><span class="p">);</span>
557</pre></div>
558</div>
559<p>Where filename is the name of the file you wish to load (without the
560file extension), and language is the language set containing it (ie,
561english). If the second parameter is missing, the default language set
562in your <strong>application/config/config.php</strong> file will be used.</p>
563<p>You can also load multiple language files at the same time by passing an array of language files as first parameter.</p>
564<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">lang</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="k">array</span><span class="p">(</span><span class="s1">&#39;filename1&#39;</span><span class="p">,</span> <span class="s1">&#39;filename2&#39;</span><span class="p">));</span>

574<p>Once your desired language file is loaded you can access any line of
575text using this function:</p>
576<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">lang</span><span class="o">-&gt;</span><span class="na">line</span><span class="p">(</span><span class="s1">&#39;language_key&#39;</span><span class="p">);</span>
577</pre></div>
578</div>
579<p>Where <em>language_key</em> is the array key corresponding to the line you wish
580to show.</p>
581<p>You can optionally pass FALSE as the second argument of that method to
582disable error logging, in case you’re not sure if the line exists:</p>
583<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">lang</span><span class="o">-&gt;</span><span class="na">line</span><span class="p">(</span><span class="s1">&#39;misc_key&#39;</span><span class="p">,</span> <span class="k">FALSE</span><span class="p">);</span>
