uniqueStrict

uniqueStrict 方法的使用和 unique 方法类似，只是使用了「严格」比较来过滤。

collect([1, '1', 2, 2, 3, 4, '2'])->unique();

// [1, '1', 2, 3, 4, '2']

自定义键

collect([
    ['name' => 'iPhone 12', 'status' => 1],
    ['name' => 'iPhone 13', 'status' => '1'],
    ['name' => 'iPhone 14', 'status' => 1]
])->uniqueStrict('status');

// [
//  ['name' => 'iPhone 12', 'status' => 1],
//  ['name' => 'iPhone 13', 'status' => '1']
//]

自定义回调

collect([
  ['name' => 'iPhone 6', 'brand' => 'Apple', 'type' => 'phone'],
  ['name' => 'iPhone 5', 'brand' => 'Apple', 'type' => 'phone'],
  ['name' => 'Apple Watch', 'brand' => 'Apple', 'type' => 'watch'],
  ['name' => 'Galaxy S6', 'brand' => 'Samsung', 'type' => 'phone'],
  ['name' => 'Galaxy Gear', 'brand' => 'Samsung', 'type' => 'watch'],
])->uniqueStrict(fn ($item) => $item['brand'] . $item['type']);

/*
[
    ["name" => "iPhone 6", "brand" => "Apple", "type" => "phone"],
    ["name" => "Apple Watch", "brand" => "Apple", "type" => "watch"],
    ["name" => "Galaxy S6", "brand" => "Samsung", "type" => "phone"],
    ["name" => "Galaxy Gear", "brand" => "Samsung", "type" => "watch"]
]
*/
