使用另一个多维数组名称填充多维数组阵列

Question

我试图将人$prides从一个多维数组分配给另一个多维数组中的房间$campus。

第一个数组中的人首先被分组为编码数组，指示他们的建筑物偏好，房间偏好和性别。

我需要首先匹配适当的数组，即获得建筑物中大房间的人数组，这将是bldgaLargeF和bldgaLargeM。然后填满每个房间，直到我用完女性，剩下的床铺留空，然后用男性填充隔壁房间。如果我在用完人之前耗尽了房间，剩下的人需要被安置到无家可归的人群中。

房间数量是固定的，人数或甚至人数组中的组数可能会有所不同。

我该如何写这个而不会创建一个恶作剧或建立数百个嵌套的if和case语句？

<?php 
/* 
    - multidimensional array of people 
     - group by requirements: building, room size, smoking, roommate smoking preference 
    - multidimensional array of rooms 
     - group by building, size, bunks 
    - break arrays into sets 
     - count number of people in each set 
     - reserve block of required rooms 
     - assign remaining people to homeless array

$prides = array(
    "acbLargeM" => array("Matt","Jason","Tim","Jeffrey","Ed","Jim"), 
    "acbLargeF" => array("Andrea","Ashley","Renae","Dena","Amanda","Amie","Angie"),

我可能会做这样的：与$prides阵列

• 工作，并删除每个人是进入一个房间。所以最终无家可归的人仍然是这个阵列中的人。
• 通过引用使用$campus数组，并直接填充它。

foreach($campus as $building => &$buildings) { 
    foreach($buildings as $size => &$sizes) { 
     foreach($sizes as $roomno => &$room) { 
      // build the pride string of this room 
      $roomPride = $building . $size; 
      // check if there is the pride of this room defined - if not: continue with the next room 
      if(!array_key_exists($roomPride.'F',$prides) && !array_key_exists($roomPride.'M',$prides)) continue; 
      // determine the gender for this room 
      $roomGender = (!empty($prides[$roomPride.'F'])) ? 'F' : 'M'; 
      // loop over the room size 
      foreach($room as &$space) { 
       // check weather there are people left that fit this room's "settings" 
       if(!empty($prides[$roomPride.$roomGender])) { 
        // if so, place the people in and remove them from the $prides array 
        $space = $prides[$roomPride.$roomGender][0]; 
        array_splice($prides[$roomPride.$roomGender], 0, 1); 
       } 
      } 
     } 
    } 
} 
// flatten the $prides array to get all homeless people 
$homeless = call_user_func_array('array_merge', $prides);
