gettext problem in codeigniter

Question

I added one library for gettext translation. Added corresponding po and mo files.

And the translation is working fine.

Now when I update my po file, change some translation.. after that when I reload the page, I am getting the old translation, not the new.

Here is the Library code:

/**
 * This method overides the original load method. Its duty is loading the domain files by config or by default internal settings.
 *
 */
function load_gettext($userlang = false) {

    /* I want the super object */
    if ($userlang)
        $this->gettext_language = $userlang;
    else
        $this->gettext_language = 'it_IT';
    log_message('debug', 'Gettext Class gettext_language was set by parameter:' . $this->gettext_language);

    putenv("LANG=$this->gettext_language");
    setlocale(LC_ALL, $this->gettext_language);

    /* Let's set the path of .po files */
    $this->gettext_path = APPPATH . 'language/locale';
    log_message('debug', 'Gettext Class path chosen is: ' . $this->gettext_path);

    bindtextdomain($this->gettext_domain, $this->gettext_path);
    textdomain($this->gettext_domain);
    log_message('debug', 'Gettext Class the domain chosen is: ' . $this->gettext_domain);
    return true;
}

/**
 *  Plural forms added by Tchinkatchuk
 *  http://www.codeigniter.com/forums/viewthread/2168/
 */

/**
 * The translator method
 *
 * @param string $original the original string to translate
 * @param array $aParams the plural parameters
 * @return the string translated
 */
function _trans($original, $aParams = false) {
    if (isset($aParams['plural']) && isset($aParams['count'])) {
        $sTranslate = ngettext($original, $aParams['plural'], $aParams['count']);
        $sTranslate = $this->replaceDynamically($sTranslate, $aParams);
    } else {
        $sTranslate = gettext($original);
        if (is_array($aParams) && count($aParams))
            $sTranslate = $this->replaceDynamically($sTranslate, $aParams);
    }
    return $sTranslate;
}

This is the usage in a controller:

$this->pos_language->load_gettext('fr_FR');
echo $this->pos_language->_trans('Hello world, good morning');

I think you need to compile your .po files to .mo files. Gettext uses the .mo file, the .po is just a human readable form.

If you haven't done the compilation step, your application is still reading your old .mo files, with the untranslated strings...
