    You have to use isset()

    $prices = array(); 

if(isset($property_type['price1'])) array_push($prices, $property_type['price1']);

    Try This

    $prices=array();

if (isset($property_type['price1']) && $property_type['price1'] !== null) {

  $price1=$property_type['price1'];
  array_push($prices, $price1);

}

    You should not assign to $price1 without knowing whether $property_type[‘price1’] is empty or nonempty. First, you should query whether $property_type[‘price1’] is empty or nonempty.

    you can code:

    $prices=array();
if(!empty($property_type['price1'])){
 array_push($prices, $property_type['price1']);
}

    This error could be triggered if $property_type['price1'] is null or not set. Make sure it is set before trying to access it as an array element

    $prices = array();
if (isset($property_type['price1'])) {
    $price1 = $property_type['price1'];
    if (!empty($price1)) {
        array_push($prices, $price1);
    }
}
