通过索引合并两个数组 [英] Merging two arrays by index

问题描述

好吧，如果感觉像这样应该很简单并且可以通过array_merge()或array_merge_recursive之类的函数来完成，但是我不太清楚.我有两个简单的数组，其结构类似于下面的(简化)示例.我只想根据它们的索引将它们合并到一个数组中.

Okay, if feel like this should be really simple and accomplished by a function like array_merge() or array_merge_recursive, but I can't quite figure it out. I have two simple arrays structured like the (simplified) example below. I simply want to merge them into one array based on their index.

$ array 1:

Array ( 
  [0] => Array ( 
        [ID] => 201 
        [latLng] => 45.5234515, -122.6762071 
  )  
  [1] => Array ( 
        [ID] => 199 
        [latLng] => 37.7931446, -122.39466520000002 
  )
) 

等等...

$ array2:

Array ( 
  [0] => Array ( 
        [distance] => 1000 
        [time] => 10 
  )  
  [1] => Array ( 
        [distance] => 1500 
        [time] => 15 
  )
) 

$ desiredResult:

Array ( 
  [0] => Array ( 
        [ID] => 201 
        [latLng] => 45.5234515, -122.6762071 
        [distance] => 1000 
        [time] => 10 
 )  
  [1] => Array ( 
        [ID] => 199 
        [latLng] => 37.7931446, -122.39466520000002 
        [distance] => 1500 
        [time] => 15 
 )
) 

当我尝试使用合并功能合并这些内容时，我只能得到以下内容:

When I try to merge these using merge functions, I can only get this:

$ unDesiredResult:

Array ( 
  [0] => Array ( 
        [ID] => 201 
        [latLng] => 45.5234515, -122.6762071 
  )  
  [1] => Array ( 
        [ID] => 199 
        [latLng] => 37.7931446, -122.39466520000002 
  )
  [2] => Array ( 
        [distance] => 1000 
        [time] => 10 
  )  
  [3] => Array ( 
        [distance] => 1500 
        [time] => 15 
  )
) 

我是否需要循环以将第二组推入第一组，还是可以使用现有功能来完成?

Do I need to loop through to push the second set into the first, or can this be done with an existing function?

推荐答案

我认为没有为您执行此操作的函数，您将需要循环.

I don't think there is a function to do this for you, you're gonna have to loop.

$result = array();
foreach($array1 as $key=>$val){ // Loop though one array
    $val2 = $array2[$key]; // Get the values from the other array
    $result[$key] = $val + $val2; // combine 'em
}

或者您可以将数据放入$ array1，因此您需要制作第三个数组:

Or you can push the data into $array1, so you need to make a 3rd array:

foreach($array1 as $key=>&$val){ // Loop though one array
    $val2 = $array2[$key]; // Get the values from the other array
    $val += $val2; // combine 'em
}
