A non well formed numeric value encountered After Formatted by number_format() function

Question

I am using Accessor for format my number value. Problem start when i try to calculate the formatted value because number_format() function return a string value. Is there any alternative way to format the number value and calculate the value also.

class Order extends Model

{
    protected $fillable = ['order_quantity'];

    public function getOrderQuantityAttribute($value)
    {
        return number_format($value);
    }
}

Error shown when i try to calculate like,

$order->order_quantity * 100;   
//$order->order_quantity value is 10,000

Answer 1

may be this will help you. using str_replace remove comma from string.

$newOrderQuantity = str_replace(',', '', $order->order_quantity); // converting to "10000"

so on, you can use (int)$newOrderQuantity for calculation.
