如何從下面的陣列中獲取 id 引數： 當我傳遞引數 1 時，我只想獲取第一個元素，當 id 為 2 時，我獲取陣列的第 2 項
public function payments($id){
$data = [
['id' => 1, 'amount' => '22000', 'name' => 'ken'],
['id' => 2, 'amount' => '24000', 'name' => 'ken'],
['id' => 3, 'amount' => '26000', 'name' => 'ken'],
['id' => 4, 'amount' => '2000', 'name' => 'tom'],
];
return $data->find($id);
}

由于我們使用的是多維陣列，因此我們可以使用array_searchwith array_column。
$data = [
['id' => 1, 'amount' => '22000', 'name' => 'ken'],
['id' => 2, 'amount' => '24000', 'name' => 'ken'],
['id' => 3, 'amount' => '26000', 'name' => 'ken'],
['id' => 4, 'amount' => '2000', 'name' => 'tom'],
];
$key = array_search($id, array_column($data, 'id'));
echo var_dump($data[$key]);

如果你想要一個使用集合的“Laravel”替代解決方案
public function payments($id){
$data = [
['id' => 1, 'amount' => '22000', 'name' => 'ken'],
['id' => 2, 'amount' => '24000', 'name' => 'ken'],
['id' => 3, 'amount' => '26000', 'name' => 'ken'],
['id' => 4, 'amount' => '2000', 'name' => 'tom'],
];
$data = collect($data);
return $data->where('id', $id)->first();
}
