Question

I am using a translator class i found online. It works phenomenally when I use it to directly echo the message. The problem occurs when I do conditional checks at the beginning of the page and I need to have the translated text in the variable to then send it to other places on the page to be displayed.

My code:

if ($condition_1){
    $message = $translate->__('Text 1');
}

elseif ($condition_2){
    $message = $translate->__('Text 2');
}

elseif ($condition_3){
    $message = $translate->__('Text 3');
}

This code echos the text in the place where this condition is put, not used as the variable $message and then echos when I need it to. Can you help me to figure out how to use the text as a variable.

If I use the text with no translator class. I can easily use it as a variable.

This is the class i use:

class Translator {

    private $language   = 'sl';
    private $lang       = array();

    public function __construct($language){
        $this->language = $language;
    }

    private function findString($str) {
        if (array_key_exists($str, $this->lang[$this->language])) {
            echo $this->lang[$this->language][$str];
            return;
        }
        echo $str;
    }

    private function splitStrings($str) {
        return explode('=',trim($str));
    }

    public function __($str) {  
        if (!array_key_exists($this->language, $this->lang)) {
            if (file_exists($this->language.'.txt')) {
                $strings = array_map(array($this,'splitStrings'),file($this->language.'.txt'));
                foreach ($strings as $k => $v) {
                    $this->lang[$this->language][$v[0]] = $v[1];
                }
                return $this->findString($str);
            }
            else {
                echo $str;
            }
        }
        else {
            return $this->findString($str);
        }
    }
}

The translated text is in the a *.txt file, looking like this:

text 1=text 1 translated
text 2=text 2 translated
text 3=text 3 translated

The problem was in the "echo" in the class. I changed the "echo" with "return" and it works like a charm!
