Question

我试图在循环内的关联数组中添加两个键和值，但我无法使其工作。

目前这是我的代码：

$bedrijven            = "
select
  cnt.id, cnt.title, cnt.introtext, cnt.ordering, cnt.state, f.item_id,
  max(case when f.field_id = 3 then f.value end) as plaats,
  max(case when f.field_id = 1 then f.value end) as straat
from snm_fields_values f
join snm_content cnt
on cnt.id = f.item_id
where cnt.state = 1
group by f.item_id
order by f.item_id, plaats, straat";
$bedrijvencon       = $conn->query($bedrijven);
$bedrijvenarray = [];
while($bedrijven    = $bedrijvencon->fetch_assoc()){
   array_push($bedrijvenarray, $bedrijven);
   $straatnaam = str_replace(' ', '+', $bedrijven['straat']);
   $bedrijflijst .= $bedrijven['plaats'].$straatnaam.'<br>';
   $getlatlong = file_get_contents("https://maps.googleapis.com/maps/api/geocode/json?address=".$bedrijven['plaats'].",".$straatnaam."&key=myapikey");
   $latlongarray = json_decode($getlatlong);
   $lat = '';
   $lng = '';
   foreach ($latlongarray->results as $key => $latlong){
    //  $latlonglijst .= $latlong->geometry->location->lat.'&nbsp;';
    //  $latlonglijst .= $latlong->geometry->location->lng.'<br>';
    $lat .= $latlong->geometry->location->lat;
    $lng .= $latlong->geometry->location->lng;
    // array_push($bedrijvenarray, $lat, $lng);
    $new_array = array('lat'=>''.$lat.'', 'lng'=>''.$lng.'');

   }
   $merged_array = array_merge($new_array,$bedrijvenarray);
}
$jsonobject = json_encode($bedrijvenarray);

echo '<pre>';
print_r($merged_array);
echo '</pre>';

返回以下内容：

正如您所看到的那样，lat和long不合适，只加载一次。每个项目都需要有自己的纬度，如下所示：

[6] => Array
            (
                [id] => 9
                [title] => Molengraaf Makelaardij
                [introtext] => 
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus 

                [ordering] => 0
                [state] => 1
                [item_id] => 9
                [plaats] => Zuidland
                [straat] => Mr. P.J. Oudweg 56
                [lat] => 51.8214507
                [lng] => 4.2591759
            )

我做错了什么？我已经尝试了array_push但这显示了键作为数字，我需要它们是文本（lat，lng），因为这是我以后使用javascript的方式。像我现在使用的array_merge也没有给出我需要的结果。

不是使用array_push，而是手动执行，

while($bedrijven    = $bedrijvencon->fetch_assoc()){
   $straatnaam = str_replace(' ', '+', $bedrijven['straat']);
   $bedrijflijst .= $bedrijven['plaats'].$straatnaam.'<br>';
   $getlatlong = file_get_contents("https://maps.googleapis.com/maps/api/geocode/json?address=".$bedrijven['plaats'].",".$straatnaam."&key=myapikey");
   $latlongarray = json_decode($getlatlong);
   $lat = '';
   $lng = '';
   foreach ($latlongarray->results as $key => $latlong){
    //  $latlonglijst .= $latlong->geometry->location->lat.'&nbsp;';
    //  $latlonglijst .= $latlong->geometry->location->lng.'<br>';
    $lat .= $latlong->geometry->location->lat;
    $lng .= $latlong->geometry->location->lng;
    // array_push($bedrijvenarray, $lat, $lng);
    $new_array = array('lat'=>''.$lat.'', 'lng'=>''.$lng.'');

   }
   $merged_array = array_merge($new_array,$bedrijvenarray);
   // Check the change below this line.
   $bedrijven['lat'] = $new_array['lat'];
   $bedrijiven['lng'] = $new_array['lng'];
   $bedrijvenarray[] = $bedrijven;
}
