CI Language Extended

Category:Core | Category:Core::Community | Category:Core::Language

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 had 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: [code] //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 --! [/code]

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: [code] //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?"; [/code]

The actual library is the following: [code] 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;
}

} [/code]
