我想比较两个集合并在标签中显示新记录和更改。我有两个标签显示新的和更改记录。我只会展示新的和记录的变化。

我使用嵌套循环来比较和突出显示更改，但有没有方法只显示更改并将其分配给不同选项卡的新记录和记录？

// want to compare
$reader = \Excel::load(Input::file('import_file'))->toArray(); 
$result = DB::table('items')->select('....')->get();

基于给定数组的工作解决方案：

$db = array_map('serialize', $db);
$excel = array_map('serialize', $excel);
$diff = array_map('unserialize', array_diff($excel, $db));

因此，您序列化数组。你得到一个字符串数组（序列化数组）。然后使用array_diff比较这些字符串。然后你只是反序列化结果。最后，你得到一个阵列。

如何在不同的选项卡中比较两个数组和显示集合？
