在PHP Array中访问JSON对象

I have some JS that is sending a POST request to a PHP controller. The JS code is as follows:

我有一些JS正在向PHP控制器发送POST请求。 JS代码如下：

$.ajax({
  url: 'map-controller/coordcontroller.php',
  data: {myData:JSON.stringify(myArray)},
  type: 'post',
  success: function(output) {
    console.log(output);
  }
});

On the server side, $_POST["myData"] is as follows:

在服务器端，$ _POST [“myData”]如下：

[{"lat":36.8867497490586,"lng":-76.3046246767044},{"lat":36.88671756964517,"lng":-76.30381464958191}]

As I understand it, my data resides in a single element array ($_POST["myData"]), containing a series of objects delimited by commas. I have tried json_decode() but I have a feeling it isn't working because my data object is actually an array instead of actual JSON data.

据我了解，我的数据驻留在单个元素数组（$ _POST [“myData”]）中，包含一系列以逗号分隔的对象。我尝试过json_decode（），但我觉得它不起作用，因为我的数据对象实际上是一个数组而不是实际的JSON数据。

My question: How can I access each object within a loop? Or is my implementation flawed and should I modify my Javascript to send the data differently?

我的问题：如何访问循环中的每个对象？或者我的实现有缺陷，我应该修改我的Javascript以不同的方式发送数据吗？

#1

var_dump (json_decode($_POST["myData"]));

Results in:

结果是：

array(2) {
  [0]=>
  object(stdClass)#1 (2) {
    ["lat"]=>
    float(36.886809817261)
    ["lng"]=>
    float(-76.304672956467)
  }
  [1]=>
  object(stdClass)#2 (2) {
    ["lat"]=>
    float(36.886146919127)
    ["lng"]=>
    float(-76.305075287819)
  }
}

My mistake was using echo instead of var_dump to check the decoded object.

我的错误是使用echo而不是var_dump来检查解码的对象。

var_dump (json_decode($_POST["myData"]));
