Multiple languages

[arnage]

Here are used tree languages in files srpski.php , english.php , spain.php stored in /translate/ folder, srpski.php (sr) is default.

$lang = isset($_GET['lang']) ? trim($_GET['lang']) : 'sr';

$langs = array('sr' => 'srpski', 'en' => 'english', 'sp' => 'spain');

if (!empty($lang) && !preg_match('/^[a-z]+$/D', $lang) || strlen($lang) > 2) { exit; }

if (isset($lang) && array_key_exists($lang, $langs)) {
$token_lang = $langs[$lang];
if (is_file($_SERVER['DOCUMENT_ROOT'].'/translate/'.$token_lang.'.php')) { require_once($_SERVER['DOCUMENT_ROOT'].'/translate/'.$token_lang.'.php'); }
} else {
if (is_file($_SERVER['DOCUMENT_ROOT'].'/translate/srpski.php')) { require_once($_SERVER['DOCUMENT_ROOT'].'/translate/srpski.php'); }
} 

Files srpski.php , english.php , spain.php are for smaller translations like link names, categories, title... and contains something like:

$tlang = array();
$tlang['home'] = 'Home';
$tlang['back'] = 'Back';
$tlang['wallpapers'] = 'Free Wallpapers';
// ... 

This function is for translation pages, to open the folder and include specified tpl file in case of choosen language.

function get_lng_inc($inc_folder, $inc_file) { global $lang;
if ($lang == 'en' || $lang == 'sp') {
if (is_file($_SERVER['DOCUMENT_ROOT'].'/'.$inc_folder.'/'.$lang.'/'.$inc_file.'.tpl')) { require_once($_SERVER['DOCUMENT_ROOT'].'/'.$inc_folder.'/'.$lang.'/'.$inc_file.'.tpl'); }
} else {
if (is_file($_SERVER['DOCUMENT_ROOT'].'/'.$inc_folder.'/sr/'.$inc_file.'.tpl')) { require_once($_SERVER['DOCUMENT_ROOT'].'/'.$inc_folder.'/sr/'.$inc_file.'.tpl'); }
}
} 

For example folder structure like:
root/folder/subfolder1/sr/file.tpl
en/file.tpl
sp/file.tpl
/folder/subfolder2/sr/file.tpl
en/file.tpl
sp/file.tpl
... usage for the function when ur in /folder/ index.php is:

    echo head($tlang['PageTitle']);

echo get_lng_inc('subfolder2', 'file');

    echo foot(); 

Usage:

if ($lang == 'en') {
echo '
<a href="./index.php?lang=sr">Srpski</a>
<a href="./index.php?lang=sp">Espańol</a>';
}
elseif ($lang == 'sp') {
echo '
<a href="./index.php?lang=en">English</a>
<a href="./index.php?lang=sr">Srpski</a>';
} else {
echo '
<a href="./index.php?lang=en">English</a>
<a href="./index.php?lang=sp">Espańol</a>';
}
