Добрый день! Подскажите как избавиться от лишних символов в URL. Ссылки в навигации получаются тако...

?foto=Y&%3Ffoto=Y&PAGEN_1=3&SIZEN_1=12
?foto=Y&price_asc=Y&%3Ffoto=Y&PAGEN_1=5&SIZEN_1=1

$arUrlRewrite = array(
   array(
      "CONDITION" => "#^/([0-9a-zA-Z_-]+)/([0-9a-zA-Z_-]+)/([0-9a-zA-Z_-]+)/([0-9a-zA-Z_-]+)/?#",
      "RULE" => "CITY_CODE=\$1&SECTION_CODE=\$2&SECTION_CODE_2=\$3&ELEMENT_CODE=\$4&\$5",
      "ID" => "",
      "PATH" => "/section/detail.php",
   ),
   array(
      "CONDITION" => "#^/([0-9a-zA-Z_-]+)/([0-9a-zA-Z_-]+)/?#",
      "RULE" => "CITY_CODE=\$1&SECTION_CODE=\$2&\$3",
      "ID" => "",
      "PATH" => "/section/index.php",
   ),
   array(
      "CONDITION" => "#^/([0-9a-zA-Z_-]+)/?#",
      "RULE" => "CITY_CODE=\$1&\$3",
      "ID" => "",
      "PATH" => "/section/index.php",
   ),
);
