如何访问名称无效的属性？

问题描述：

我要向将要通过第三方API发送的stdClass对象添加数据，因此我给这个对象的元素的名称实际上是由该外部服务定义的。

I'm adding data to a stdClass object that is going to be sent through a 3rd party API and so the names I am giving to the elements of this object are actually being defined by that external service.

$insertArray = array();
$insertArray[0] = new stdclass();
$insertArray[0]->Name = $name;
$insertArray[0]->PhoneNumber = $phone;

这一切都在奇妙地工作，直到我碰到一个属性无效的名称：

This was all working wonderfully until I came across a property with an invalid name:

$insertArray[0]->First.Name = $firstname;

所以这不是有效的PHP语法，

So that isn't valid PHP syntax, so is there a way around this?

答

感谢评论（@AbraCadaver），复杂（curly）语法是去无效变量或属性名称的方法：

Thanks to the comments (@AbraCadaver), Complex (curly) syntax is the way to go for invalid variables or property names:

$insertArray[0]->{"First.Name"} = $firstname;
