只是尝试从我们的API返回json中的价格,这需要格式化为带有两个小数位的浮点数。目前,当我浮动它返回没有小数但没有浮点数它返回一个字符串,我希望它作为一个浮点数。
public function repairs(Collection $repairs) : Collection
{
return $repairs->map(function ($repair) {
return [
"id" => $repair->id,
"title" => $repair->problem->title,
"price" => (float) $repair->price
];
});
}
结果:
"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
}
}

您可以使用round()或number_format()。 Round返回一个float,number_format返回一个字符串。所以你可能更喜欢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) ]; }); }
