Question

I’ve language files like “en.lang.php”:

/* english language */
return array(
    "random.key.one" => "random value one", 
    "random.key.two" => "random value two);

Usage (the quick & dirty way):

/* random_template.php */
$language = "en";
$file = $language . ".lang.php";
$text = include($file);
echo $text["random.key.one"]; // "random value one"

Question:
How is it possible to use this values in JavaScript?

Idea:
Generate en.lang.js with a function that returns the needed value, usage:

alert(get_text("random.key.one"));

Problem: I’ve to flush the cache everytime the *.lang.php-file was changed. Not that user-friendly.

Thanks in advance!

If you’re using PHP >= 5.2.1 (.0, technically), the easiest way I can imagine is as follows:

Have a file that generates a JSON-array with

echo 'set_text(' . json_encode(include($file)) . ')';

JavaScript-wise:

var texts = [];
function set_text(languageTexts){
  texts = languageTexts;
}
function get_text(key) {
  return texts[key];
}
