Case insensitive in array

We have the following code in opencart that specifies postcodes that do not receive free postage:

foreach ($results as $result) {
  if ($this->config->get($result['code'] . '_status')) {
    $noFreeDelivery = false;

    if ($result['code'] == 'free') {
      $disallowedFreePostcodes = array(
        'IV', 'BT', 'HS', 'KA27', 'KA28', 'KW', 'PA20', 'PA21', 'PA22', 'PA23', 'PA24', 'PA25', 'PA26', 'PA27', 'PA28', 'PA29', 'PA30', 'PA31', 'PA32', 'PA33', 'PA34', 'PA35', 'PA36', 'PA37', 'PA38', 'PA39', 'PA40', 'PA41', 'PA42', 'PA43', 'PA44', 'PA45', 'PA46', 'PA47', 'PA48', 'PA49', 'PA60', 'PA61', 'PA62', 'PA63', 'PA64', 'PA65', 'PA66', 'PA67', 'PA68', 'PA69', 'PA70', 'PA71', 'PA72', 'PA73', 'PA74', 'PA75', 'PA76', 'PA77', 'PA78', 'PH17', 'PH18', 'PH19', 'PH20', 'PH21', 'PH22', 'PH23', 'PH24', 'PH25', 'PH26', 'PH30', 'PH31', 'PH32', 'PH33', 'PH34', 'PH35', 'PH36', 'PH37', 'PH38', 'PH39', 'PH40', 'PH41', 'PH42', 'PH43', 'PH44', 'PH49', 'PH50', 'ZE', 'BT', 'IM', 'TR21', 'TR22', 'TR23', 'TR24', 'TR25', 'AB31', 'AB33', 'AB34', 'AB35', 'AB36', 'AB37', 'AB38', 'AB45', 'AB52', 'AB53', 'AB54', 'AB55', 'AB56', 'FK', 'Ph33'
      );

      foreach ($disallowedFreePostcodes as $postcode) {
        $range = explode('-', $postcode);

        if (array_key_exists(1, $range)) { 
          $start = str_split($range[0], 2);

          foreach (range($start[1], $range[1]) as $postcodeSuffix) {
            $code = $start[0].$postcodeSuffix;

            if (strpos($this->session->data['shipping_address']['postcode'], $code) === 0) {
              $noFreeDelivery = true;
              break;
            }
          }

          continue;
        }

        if (strpos($this->session->data['shipping_address']['postcode'], $range[0]) === 0) {
          $noFreeDelivery = true;
          break;
        }
      }
    }
  }

The problem I'm facing is that if someone, for example, entered pa22 (lowercase) or Pa22 (mixed cases) they would still be offered the free shipping. Can someone suggest a way in which I can get the code to discount case without having to add every possible input to the array?

TIA

You must convert array values to lower and convert entered value to lower too, after that you can check easily.

For example,in this code snippet:

strpos($this->session->data['shipping_address']['postcode'], $code)

you must do like this:

strpos(strtolower($this->session->data['shipping_address']['postcode']), strtolower($code))
