I am using a lot the Language library and i realized that it needs some improvments to be more effecient.
So i have done some modifications to it by extending the CI_Language library and overloading the CI_Language::line() method.
I have added two more features to it:
1) echo a “language string” (key) when it isn’t exists rather than echoing null
so we can realize which lang strings hasn’t translated yet
e.g:
//when we use the following line of code
echo $this->lang->line("lang_string_key");
//we should get
//NORMAL OUTPUT: false
//but
//MODIFIED OUTPUT: !-- lang_string_key --!
2)Many times i wanted to pass some variables into some translated lines.
So i have added a second optional variable that pass a value or an array to be inserted inside the translated line
e.g:
//in some language file we add a line as the one that follows
$lang['some_line'] = "Hello $1, do you want some $2?";
//when we want to get the translation we can add the following code
echo $this->lang->line('some_line', array('George', 'tea'));
//the output should be: "Hello George, do you want some tea?";
The actual library is the following:
class MY_Language extends CI_Language{
function line($line, $params=null){
$return = parent::line($line);
if($return === false){
return "!-- $line --!";
}else{
if (!is_null($params)){
$return = $this->_ni_line($return, $params);
}
return $return;
}
}
private function _ni_line($str, $params){
$return = $str;
$params = is_array($params) ? $params : array($params);
$search = array();
$cnt = 1;
foreach($params as $param){
$search[$cnt] = "/\\\${$cnt}/";
$cnt++;
}
unset($search[0]);
$return = preg_replace($search, $params, $return);
return $return;
}
}
