php - set a class property as a float or decimal value when being echo'd

Question

i'm curious how something like this would work

class Test
{
    public $price;
}

$obj = new Test();
$obj->price = 4500.00;

echo $obj->price;

how can I return that value as 4500.00 and not 4500?

Answer 1

echo number_format($obj->price,2);

If you don't what the thousands seperator:

echo number_format($obj->price,2,'.','');

See number_format
