我有一个这样的对象：

dotnet doesthiswork.dll

我想循环遍历此对象的所有元素，使其具有以下内容：

Your app failed to make an outbound TCP connection because the machine-wide TCP Connection limit was hit

但如果我像这样循环我的对象：

    myObj = {"id":12,"title":"my title","content":"my content"}

我得到了这个结果：

    echo " $key ." = ". $value

    result : id = 12
             title = my title
             content = my content

如何获取对象的元素？

1 个答案:

答案 0 :(得分：2)

检查此代码：

$myObj = '{"id":12,"title":"my title","content":"my content"}';

$object = json_decode($myObj);

foreach($object as $key => $value) {
  echo $key . " = " . $value . "<br>";
};
