我的问题可能会让某些人感到困惑。但实际上这是一个非常简单的。让我给你解释一下场景。我有一个名为$test_result_data 的数组，如下所示：

现在你可以看到这个数组里面有两个主数组。这些数组中的每一个都包含测试包数据。这个数组是动态创建的，所以我们不能说每次它包含多少个项目。现在我有一个$test_pack_id，我只想从上面的数组中获取那些数组元素，其中键[test_pack_id] 的值与变量$test_pack_id 的值相匹配。我想为这些匹配的测试包数据项创建一个全新的数组。任何人都可以帮我获得这个数组吗？
假设我有以下变量：
$test_pack_id = '84880f321fc957f9b28b702d5a43f57b';//This is my input
数组$test_result_data 可以在其元素中包含此id 一次、多次或不包含。但是如果找到匹配，那么它应该返回所有匹配的元素。在上述情况下，输出应如下所示：
