data_fill

Logo laravel/framework laravel/framework
The data_fill function sets a missing value within a nested array or object using "dot" notation:
<?php $data = ['products' => ['desk' => ['price' => 100]]];

data_fill($data, 'products.desk.price', 200);


data_fill($data, 'products.desk.discount', 10);
<?php     {

        $data = ['foo' => 'bar'];



        $this->assertEquals(['foo' => 'bar', 'baz' => 'boom'], data_fill($data, 'baz', 'boom'));

        $this->assertEquals(['foo' => 'bar', 'baz' => 'boom'], data_fill($data, 'baz', 'noop'));

        $this->assertEquals(['foo' => [], 'baz' => 'boom'], data_fill($data, 'foo.*', 'noop'));
