通过引用传递的PHP函数无法显示数组的整个元素

I don't think if my code was correct but i'd reviewed PHP manual in function passe by reference. I don't think if i have missed something but can't figure it out..

my function is here:

public function display_victims(&$vName, &$vAddr, &$vAge, &$vGender){
        for ($i = 0; $i < count($vName); $i++) 
                    {
                        echo $vName[$i].'|'.$vAddr[$i].'|'.$vAge[$i].'|'.$vGender[$i];
                        return true;
        }
 }

my form was in the other file I send the form in this file named save_data.php here is the code:

$csppoAdmin = new CsppoAdmin();

 if ($_REQUEST['save']=='rc'){

      extract($_REQUEST);

     $post = $csppoAdmin->report_crime($vName, $vAddr, $vAge, $vGender)

     echo $post;

 }

when I run it the output was only one element of the array or one row only.
