Question

我有两个不同的阵列

$arr1=Array ( 'latitude' => 9.9252007, 'longitude' => 78.1197754, 'title' => 'Madurai' ) ;
$arr2=Array ( 'latitude' => 9.2323, 'longitude' => 78.23233, 'title' => 'Peraiyur' ) ;

我需要将两个数组合并为单个并需要通过json_encode转换为json，所以我的代码在这里合并数组并解析为json

$obj['markers']=(object) array( $arr1, $arr2 );

echo json_encode($obj);

输出如下

 {"markers":
 {"0":{"latitude":9.9252007,"longitude":78.1197754,"title":"Madurai"},
  "1":{"latitude":9.2323,"longitude":78.23233,"title":"Peraiyur"}} }

但我需要它像跟随

{"markers":[
  { "latitude":9.9252007, "longitude":78.1197754, "title":"Madurai"  },
  { "latitude":9.2323, "longitude":78.23233, "title":"Peraiyur" }
]}

如何删除它们？

Answer 1

为什么要投入object？如果你只是删除(object)投射，它将会完成！

$obj['markers']=array( $arr1, $arr2 );

结果：

{"markers":[{"latitude":9.9252007,"longitude":78.1197754,"title":"Madurai"},{"latitude":9.2323,"longitude":78.23233,"title":"Peraiyur"}]}

Answer 2

$obj['markers']=array( $arr1, $arr2 );

Answer 3

这个对象：

{"markers":[
  { "latitude":9.9252007, "longitude":78.1197754, "title":"Madurai"  },
  { "latitude":9.2323, "longitude":78.23233, "title":"Peraiyur" }
]}

与：

相同

print_r(json_encode(array('markers' => array($arr1, $arr2))));

因此，无需进行任何额外的复杂编码。

Answer 4

试试这个

$arr1=Array ( 'latitude' => 9.9252007, 'longitude' => 78.1197754, 'title' => 'Madurai' ) ;
$arr2=Array ( 'latitude' => 9.2323, 'longitude' => 78.23233, 'title' => 'Peraiyur' ) ;
$obj['markers']=array($arr1, $arr2);
echo json_encode($obj);

输出

{"markers":[{"latitude":9.9252007,"longitude":78.1197754,"title":"Madurai"},{"latitude":9.2323,"longitude":78.23233,"title":"Peraiyur"}]}

Answer 5

这是必须的：

$obj['markers']=array(
        array(
        'latitude' => $entity->getLat(),
        'longitude' => $entity->getLng(),
        'title' => $entity->getTitle(),
        )
    );
$json = json_encode($obj);
$response = new Response($json);
$response->headers->set('Content-Type', 'application/json');
return $response;

它将生成这个json文件：

{"markers":[{"latitude":"36.80610237001900","longitude":"10.17517220741000","title":"Mon annonce"}]}

如何使用php删除json_encode中的数组对象索引？
