str_getcsv中的函数参数

Question

I tried use function parameter $separator instead ";" in str_getcsv function but I got an error. Do you have any ideas what Can I do with it? I must read a few CSV files with diffrent separators. Error code: Undefined variable: separator in .. number on line 59

function CSV2DB($producent,$znak='',$separator,$ilosc_col) {
  $time_start = microtime(true); 
  ini_set('max_execution_time', 50000); //wydłużenie czasu wykonania
global $pdo;
$log ="";
$count = 0;
$edit_date = date("Y-m-d H:i:s");
    $dane = array();
    $dir = 'C:\\xampp\\htdocs\\Prusik\\csv\\';
    //sciezka do pliku
    $real_path = $dir . $producent . '.csv';
//csv do tabeli
     $data = array_map(
       function($v)
     {
       return str_getcsv($v, ";");
    }, file($real_path));
