Merging two arrays by index
提问by Kerri
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.
好吧，如果觉得这应该很简单，并且可以通过像array_merge()or 之类的函数来完成array_merge_recursive，但我不太明白。我有两个简单的数组，其结构类似于下面的（简化的）示例。我只是想根据它们的索引将它们合并到一个数组中。
$array 1:
$数组1：
Array (
[0] => Array (
[ID] => 201
[latLng] => 45.5234515, -122.6762071
)
[1] => Array (
[ID] => 199
[latLng] => 37.7931446, -122.39466520000002
)
)
et cetera…
等等…
$array2 :
$array2 ：
Array (
[0] => Array (
[distance] => 1000
[time] => 10
)
[1] => Array (
[distance] => 1500
[time] => 15
)
)
$desiredResult :
$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
)
)
When I try to merge these using merge functions, I can only get this:
当我尝试使用合并函数合并这些时，我只能得到这个：
$unDesiredResult:
$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
)
)
Do I need to loop through to push the second set into the first, or can this be done with an existing function?
我是否需要循环将第二组推入第一组，还是可以使用现有函数完成？

I don't think there is a function to do this for you, you're gonna have to loop.
我不认为有一个函数可以为你做这件事，你将不得不循环。
$result = array();
foreach($array1 as $key=>$val){ // Loop though one array
$val2 = $array2[$key]; // Get the values from the other array
$result[$key] = $val + $val2; // combine 'em
}
Or you can push the data into $array1, so you need to make a 3rd array:
或者您可以将数据推入 $array1，因此您需要制作第三个数组：
foreach($array1 as $key=>&$val){ // Loop though one array
$val2 = $array2[$key]; // Get the values from the other array
$val += $val2; // combine 'em
}

You'll need to use a loop. Try creating a function:
你需要使用一个循环。尝试创建一个函数：
function addArray( array &$output, array $input ) {
foreach( $input as $key => $value ) {
if( is_array( $value ) ) {
if( !isset( $output[$key] ) )
$output[$key] = array( );
addArray( $output[$key], $value );
} else {
$output[$key] = $value;
}
}
}
Then:
然后：
$combinedArray = array( );
addArray( $combinedArray, $array1 );
addArray( $combinedArray, $array2 );

example Arrays has to be merged:
示例数组必须合并：
[location_coordinates] => Array
(
[0] => 36.037939100000,-78.905221600000
[1] => 36.004398400000,-78.936084600000
)
[tm_field_reference_locations$field_location_address$city] => Array
(
[0] => Durham
[1] => Durham
)
[doctor_city] => Array
(
[0] => Durham
[1] => Durham
)
[tm_field_reference_locations$field_location_address$street] => Array
(
[0] => 407 Crutchfield Street
[1] => 40 Duke Medicine Circle
)
[tm_field_reference_locations$field_office_phone] => Array
(
[0] => 919-479-4120
[1] => 919-613-0444
)
[sm_field_reference_locations$title] => Array
(
[0] => Duke Regional Hospital Spine and Neurosciences
[1] => Duke Spine Center
)
When you loop like below:
当你像下面这样循环时：
$address= array();
for($n=0; $n<sizeof($kolDetails['location_coordinates']); $n++){
$address[$n]['org_institution_id']=$kolDetails['sm_field_reference_locations$title'][$n];
$address[$n]['longitude']=$kolDetails['location_coordinates'][$n];
$address[$n]['City']=$kolDetails['doctor_city'][$n];
$address[$n]['address1']=$kolDetails['tm_field_reference_locations$field_location_address$street'][$n];
$address[$n]['phone_number']=$kolDetails['tm_field_reference_locations$field_office_phone'][$n];
}
$kolextra['adress']=$address;
pr($kolextra['adress']);
$address = array();

I'd go about this slightly differently with an interval. This assumes your values are always locked and that the first record of array1 always corresponds with the first record of array2:
我会以稍有不同的间隔来处理这个问题。这假设您的值始终处于锁定状态，并且 array1 的第一条记录始终对应于 array2 的第一条记录：
$i = 0; // sets counter
$end = count($array1); // finds record number
while($i <= $end){ //for each record in the array
$array1[$i]['distance'] = $array2[$i]['distance']; //match up array values
$array1[$i]['time'] = $array2[$i]['time']; //match up array values
$i++; //iterate
}
Good Luck!
祝你好运！
