A long time ago I wrote a small tutorial for multilingual web sites using PHP. That tutorial is a bit outdated and unoptimized. I recently had to turn a static localized CRM into a multilanguage one. The obvious solution, without relying on gettext functions was to use PHP arrays.
So, here we go:
First of all we need a configuration setting inside our script’s config.php file. For the sake of our example, we’ll add a manual variable change:
// language settings
$lng = ‘en’;
Next, our header file, dubbed header.php (could be head.php or top.php in your script) will contain these lines:
You now, obviously, have to create a languages directory and create a new file called en.php. This file will hold our array of words and expressions:
@Package: My Multilanguage Script
@Language: English (English)
$lang = array();
$lang[‘REGISTER’] = ‘Register’;
$lang[‘USERNAME’] = ‘Username’;
$lang[‘PASSWORD’] = ‘Password’;
$lang[‘LOGIN’] = ‘Log in’;
$lang[‘LOGOUT’] = ‘Log out’;
$lang[‘DASHBOARD’] = ‘Dashboard’;
Notice how I tried to keep the array index name as close to translation as possible. For example, you’ll have the string “Separate tags with commas” as $lang[‘SEPARATE_TAGS_COMMAS’]. It’s easier after a couple of months when you’ll make changes.
Also, try to keep consistent naming of your language files, such as fr.php, de.php, ru.php, cn.php.
Now, call in you script <?php echo $lang[‘REGISTER’];?>. It will display “Register”, just as you translated it in your language file.
