PHP数组到JSON，如何摆脱一些双引号？ [英] PHP Array to json, how to get rid of some double quotes?

问题描述

在将php数组编码为json时，我遇到了一个小而奇怪的问题。

I have a small but weird problem while encoding php arrays to json.

我需要防止array（）在特定值周围添加双引号。

I need to prevent array() from adding double quotes around specific values.

这是php数组：

$coordinates="[".$row["lat"].",".$row["lng"]."]";  
$egUser=array(              

            "geometry"=>array(
                "type"=>"$type",
                "coordinates"=>$coordinates                 
        ),

            "type2"=>"$type2",
            "id"=>$id
        );
$arrayjson[]=$egUser;   

使用json_encode返回以下json：

Wich return the following json with json_encode :

var member = {
"type": "FeatureCollection",
"features": [{
    "geometry": {
        "type": "Point",
        "coordinates": "[46.004028,5.040131]"
    },
    "type2": "Feature",
    "id": "39740"
}]

};

如您所见，坐标包裹在双引号内>

As you can see the coordinates are wrapped inside double quote >

"coordinates": "[46.004028,5.040131]"

如何删除这些引号？我需要以下内容代替>

How do I get rid of these quotes ? I need to have the following instead >

"coordinates": [46.004028,5.040131]

我有点困惑，所以欢迎您提供任何帮助:)
谢谢！

I'm a bit confuse so any help is welcome :) Thank you !

推荐答案

那是因为 $ coordinates 的类型为String。

Thats because $coordinates is of type String.

$coordinates="[".$row["lat"].",".$row["lng"]."]";

创建 $ coordinates

$coordinates = array($row["lat"],$row["lng"]);
