There is such a var_damp. When executing this code:

  $min_price = Price::where('product_id','=',$id)->min('price'); $max_price = Price::where('product_id','=',$id)->max('price'); 

Instead of the minimum value of 500, it returns 10,000, and instead of 10,000 it returns 9,000. How to get min, max values ​​from this dump?
