正如您所看到的，除了$routes[ROUTE_NAME][dates]中的日期之外，两个数组元素都是相同的，我想将这些值合并为一个，这样只有一个值，除了日期之外。
例如，输出ROUTE_NAME（eq.227-DELIVERY）
[227-DELIVERY] => Array
(
[line_name] => Distribution
[pid] => 48
[rid] => 605
[level] => 1
[item_id] => 227
[subpart_id] => 227
[subpart_name] => + 1PA-E5514-00
[selected_capacity] => 1500
[capacity] => 1500
[capacity_ot2] => 0
[capacity_ot4] => 0
[dates] => Array
(
[2015-12-15] => 1200
[2015-12-16] => 1200
)
)
有没有内置的php功能呢？我不认为array_merge_recursive可以做到这一点。
答案 0 :(得分：0)
array_merge_recursive可能很麻烦，但简单的array_merge与foreach相结合会起作用。这将创建包含合并数据的新数组$result：
$result = array();
foreach($array['output'][0]['routes'] as $key => $route){
$route['dates'] = array_merge($route['dates'], $array['output'][1]['routes'][$key]['dates']);
$result[$key] = $route;
}
print_r($result);
如果你想将所有内容都放在同一个数组中，你可以这样做：
foreach($array['output'][0]['routes'] as $key => &$route){
$route['dates'] = array_merge($route['dates'], $array['output'][1]['routes'][$key]['dates']);
}
print_r($array['output'][0]['routes']);
在foreach循环中注意&，它基本上告诉我们修改我们正在循环的现有数组。
