Php返回浮动货币格式

Question

Just trying to return a price in json from our API, this needs to be formatted as a float with two decimal place. Currently when I float it returns without the decimals but without float it returns as a string and I would like it as a float.

public function repairs(Collection $repairs) : Collection
{
    return $repairs->map(function ($repair) {
        return [
            "id" => $repair->id,
            "title" => $repair->problem->title,
            "price" => (float) $repair->price
        ];
    });
}

results in:

"repairs": {
    "411": {
        "id": 411,
        "title": "Screen",
        "price": 235.99
    },
    "419": {
        "id": 419,
        "title": "Charger Port",
        "price": 40
    },
    "582": {
        "id": 582,
        "title": "Back Glass",
        "price": 40
    }
}

You can use round() or number_format(). Round returns a float, number_format returns a string. So you would probably prefer round():

    public function repairs(Collection $repairs) : Collection
    {
        return $repairs->map(function ($repair) {
            return [
                "id" => $repair->id,
                "title" => $repair->problem->title,
                "price" =>  round($repair->price,2)
            ];
        });
    }
