语言切换器，如何使用变量回显而不是_lang行的键

Question

I like to store my language lines in variables or array.

And I have this problem. How can I echo $data["menu_production"] instead of $this->lang->line("menu_production");? It works when I echo ($this->lang->line("menu_production");) but not with $data or other variable. In my controller I call this function:

function index() {
  $data["menu_production"] = $this->lang->line("menu_production");
  $this->load->view('menu', $data);
}

A quick workaround for this will be using sprintf

Let your language file has a key something like

$lang['custom_message'] = "Hello %s!";

Then use the language class as

echo sprintf($this->lang->line('custom_message'), 'world');
// output: Hello world!

$name = "John Doe";
echo sprintf($this->lang->line('custom_message'), $name);
// output: Hello John Doe!
