有没有办法按照某些标准将最多 3 个多维数组与 OOP PHP 对象组合成一个数组？

Question

 更短更通用的版本：我在 PHP 中寻找一种算法来将最多 3 个多维对象数组组合成一个多维对象数组。但是我需要一些特定的东西，所以简单的 array_merge 是不够的。如果有重复，则必须调整排名，因此该结果项需要在数组中上升。对于其他结果：它需要将相同高度的结果相互编织，而不是像 array_merge 那样将结果相互粘贴。此外，我还需要考虑到，稍后应用程序可能会通过对结果的评级进行扩展，因此排名也可能会受到基于评级的适应性调整的主观影响。Array1(Object A”Title” => ”A””Rank” => 0Object B”Title” => ”B””Rank” => 1Object C”Title” => ”C””Rank” => 2Object S”Title” =>” S””Rank” => 2)——Array 2 (Object X”Title” => X”Rank” => 0Object Z”Title” => ”Z””Rank” => 1Object C”Title” =>” C””Rank” => 2) ——Array3(Object Z”Title” => ”Z””Rank” => 0Object A”Title” => ”A””Rank” => 1Object C”Title” => ”C””Rank” => 2)- 结果应该是：combinedArray(Object C // is found by all tree”Title” => ”C””Rank” => 2Object A // is found in 2”Title” => ”A””Rank” => 0Object Z // is found in 2”Title” => ”Z””Rank” => 0Object X”Title” => X”Rank” => 0Object B”Title” => ”B””Rank” => 1Object S”Title” =>” S””Rank” => 2)__首选的回答语言是 PHP。预先感谢您的帮助并花时间阅读所有这些内容！

Answer 1

这就是我将如何解决它，这只是一个循环和最后的 usort 以根据 newRank 设置顺序。另外我假设重复的只是网址。输出链接在这里：http : //codepad.org/ClubESQ6
