with this class you can translate some parts of your site into different languages,
this class also has caching, to cache the translated results.

usage example:

PHP Code:


require_once('gtranslate.php');



$translate = new gum_translate;

$translate->to_lang = strtolower(substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,2));

$translate->cache = true;

$translate->cache_folder = 'gum_translate_cache/'; //chmod 0777 it

//echo $translate->translate('everything is ok?');

echo '<a href="http://some.site/file.php">'.$translate->translate('Download free ringtones here').'</a>';

without cache

PHP Code:


require_once('gtranslate.php');



$translate = new gum_translate;

$translate->to_lang = strtolower(substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,2));

//echo $translate->translate('everything is ok?');

echo '<a href="http://some.site/file.php">'.$translate->translate('Download free ringtones here').'</a>';

the text "Download free ringtones here" will be automatically translated into the users language, default language is english.
