whereIn方法

通过给定的键值数组来过滤集合。

$collection = collect([
    ['product' => 'Desk', 'price' => 200],
    ['product' => 'Chair', 'price' => 100],
    ['product' => 'Bookcase', 'price' => 150],
    ['product' => 'Door', 'price' => 100],
]);

$filtered = $collection->whereIn('price', [150, 200]);

$filtered->all();

/*

    ['product' => 'Bookcase', 'price' => 150],
    ['product' => 'Desk', 'price' => 200],
