Filters the collection using the given callback.

Use array_values(), array_diff() and array_filter() to filter $items based on $func.

代码实现

function reject($items, $func)
{
  return array_values(array_diff($items, array_filter($items, $func)));
}

使用样例

reject(['Apple', 'Pear', 'Kiwi', 'Banana'], function ($item) {
  return strlen($item) > 4;
}); // ['Pear', 'Kiwi']
