I managed to sort it, my question was a bit misleading. I had a calendar that was only showing 1 booked date range but that was because i had used = instead of == so now it shows all bookings
 

I've managed to sort it and it works perfectly. I've also put it into a class, here is code if anyone wants to use it.
 
Thank you for all your help!
 
 

class Calendar
{

    public static function bookedArray($strDateFrom,$strDateTo)
    {
      $aryRange = [];
      $iDateFrom = strtotime($strDateFrom);
      $iDateTo = strtotime($strDateTo);
      if ($iDateTo >= $iDateFrom) {
          array_push($aryRange, date('Y-m-d', $iDateFrom)); // first entry
          while ($iDateFrom<$iDateTo) {
              $iDateFrom += 86400; // add 24 hours
              array_push($aryRange, date('Y-m-d', $iDateFrom));
          }
      }
      return $aryRange;
    }
  
    public static function flattenCalendar($array) {
      $flatArray = [];
      array_walk_recursive($array, function($value) use (&$flatArray) {
          $flatArray[] = $value;
      });
      return $flatArray;
    }
  
    public static function estimatePrice($checkin, $checkout, $stdArray, $specArray) {
            
      $requestDates = self::bookedArray($checkin, $checkout);
      $specialRate = array();
      $standardRate = array();
      $cost = array();
      
      //return var_dump($requestDates);
      if(!empty($stdArray)) {
        foreach($stdArray as $row) {
          if($row->SeasonName == 'Standard Weekday') {
            $standardRate['Weekday'] = $row->SeasonPrice;
          }
          if($row->SeasonName == 'Standard Weekend') {
            $standardRate['Weekend'] = $row->SeasonPrice;
          }
        }
      }

      if(!empty($specArray)) {
        $i = 0;
        foreach($specArray as $row) {
            $specialRate[$i]['start'] = $row->SeasonStart;
            $specialRate[$i]['end'] = $row->SeasonEnd;
            $specialRate[$i]['price'] = $row->SeasonPrice;
          $i++;
        }
      }

      $specialCount = count($specialRate);
      $standardCount = count($stdArray);
      $flatRequest = self::flattenCalendar($requestDates); // Reqested Dated into One Array
      $cost = array();
      $specialCost = array();
      $days = count($flatRequest);

      foreach($flatRequest as $key => $val) {
        $specialDays = 0;
        for($i=0; $i<count($specialRate); $i++) {
          $range = self::bookedArray($specialRate[$i]['start'], $specialRate[$i]['end']);
          array_pop($range);
          if(in_array($val, $range)) {
            array_push($specialCost, $specialRate[$i]['price']);
            $specialDays++;
            unset($flatRequest[$key]);
          } 
        }
      }
      array_pop($flatRequest);
      foreach($flatRequest as $key => $val) {
        if( date('l', strtotime($val)) == 'Saturday' || date('l', strtotime($val)) == 'Sunday' ) {
          array_push($cost, $standardRate['Weekend']);
        } else {
          array_push($cost, $standardRate['Weekday']);
        }
      }
      
      
          
      if(!empty($cost) && !empty($specialCost)) {
        return array_sum(array_merge($cost, $specialCost));
      }
      elseif(!empty($specialCost) && empty($cost)) {
        array_pop($specialCost);
        return array_sum($specialCost);
      }
      else {
        return array_sum($cost);
      }
      
      
    }
}

Thanks you so much, i couldn't see the wood for the trees
 
i'd put $cartItems = $itemArray; instead of $cartItems[] = $itemArray; before setting the session Session::set("cart_item", $cartItems);
