Laravel 8 data_fill() {#collection-method}
2021-07-19 10:19 更新
data_fill 函数使用「.」符号给多维数组或对象设置缺省值：
$data = ['products' => ['desk' => ['price' => 100]]];
data_fill($data, 'products.desk.price', 200);
// ['products' => ['desk' => ['price' => 100]]]
data_fill($data, 'products.desk.discount', 10);
// ['products' => ['desk' => ['price' => 100, 'discount' => 10]]] 这个函数也可以接收「*」 作为通配符，并设置相应缺省值：
$data = [
'products' => [
['name' => 'Desk 1', 'price' => 100],
['name' => 'Desk 2'],
],
];
data_fill($data, 'products.*.price', 200);
/*
[
'products' => [
['name' => 'Desk 1', 'price' => 100],
['name' => 'Desk 2', 'price' => 200],
],
]
