Check if a value exists in an array and store the associative array in an array ..?

Hi,

I am a bit stuck with the following function. The goal is:
- Loop through an array which holds all products
- Divide products based on luxury vs no_luxury
- Another layout for available products, i have a seperate function for available products, it returns an associative array.

The main problem i have i can't parse the price value out of the availableProducts array.
Here's my simplified php code

<?php
$staticData = getStaticData();
$availableProducts = getAvailableProducts();

function getAllProductTypes($availableProducts, $staticData) {
    
    $allProductsTypes = array();
    $luxury = array();
    $no_luxury = array();
	
    $no_luxury_products = array('CALL','DODO','PKK','YTK','TK');
    //available products other layout with price and buy now button
    $available = array();
	//temp array for available products
    foreach($availableProducts as $value ){
        $available[] = $value['productType'];
		//HOW TO STORE an assoc array 
    }
	//get all products without price 
    $allProducts = getAllProducts();
     
	 foreach ($allProducts as $value) {
        if(in_array($value["productType"], $no_luxury_products)){
            $no_luxury[] = $value;
        } else {
            $luxury[] = $value;
        }
    }
	//div no luxury
    
	$return = '<div id="no_luxury" style="background-color:#0099FF;">';

    foreach ($no_luxury as $value) {
		//and productType is not availabe
        if(!in_array($value['RoomType'],$available)){ 
        		$return .= 'test'.$value['productType'].': '.$value['productDescr'];
        }//end not available
        else {//products ara available we have a price
				//problem i need to get the $value from the $availableProducts assoc array
            	$return .= 'Price from $availableProducts assoc Array '.$value['productPrice'].': '.$value['productDescr'].' by '.$staticData['owner'];
        }
    }
    $return .= '</div>';
	//end no luxury

	//div luxury
    $return .= '<div id="luxury" >';
    foreach ($luxury as $value) {
		//and productType is not availabe
         if(!in_array($value['RoomType'],$available)){ 
       			$return .= 'test'.$value['productType'].': '.$value['productDescr'];
         }//end not available
         else {//products ara available we have a price
		 	//problem i need to get the $value from the $availableProducts assoc array
              $return .= 'Price from $availableProducts assoc Array '.$value['productPrice'].': '.$value['productDescr'].' by '.$staticData['owner'];
         }
    }

    $return .= '</div>';
    return $return;
}
