【问题描述】：
在此函数assignView($sums,$count) 中，我想对查看次数最少的 SAP（合作伙伴）执行 INSERT INTO。
我面临的问题是从$count 数组中切出元素以便能够对其进行排序。我想我可以在 SQL 查询中对其进行排序，但切出正确的 prio 元素的问题仍然存在。
在我想要执行array_slice 的assignView($sums,$count) 函数中，一切都按预期工作。
当然，没有什么是一成不变的。如果您能看到更好或更有效的方法来实现我的目标，请随时分享:)
我正在考虑通过添加切片逻辑来修改 findKey($haystack,$needle) 函数，但由于 $count 中的 SAP 键是数字，所以我画了一个空白。
对如何解决这个问题有任何建议吗？
