PHP匿名对象-整数属性

问题描述：

我已经使用数据库中的PDO FETCH_OBJ创建了一个匿名对象.我可以使用以下方法访问大多数属性:

I've created an anonymous object, using PDO FETCH_OBJ from my DB. I can access most properties fine using:

$myObject->name;  
$myObject->age;

等

但是我的数据库中有一个以整数开头的字段. '130x90_url

But I have one field in my DB that starts with an integer. '130x90_url

当尝试访问$myObject->130x90_url;时，我得到了:

When trying to access $myObject->130x90_url; I then get :

syntax error, unexpected '130' (T_LNUMBER), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'

我在手册中看不到任何内容，但是会以为其他人会遇到此问题吗?

I can't see anything in the manual about this, but would of thought others would of come across this issue?

答

尝试一下:

echo $myObject->{'130x90_url'};

在SimpleXMLElement实例上有效，而应该在stdClass实例上有效.
可能可以在变量变量上找到更多详细信息 doc页面.

That works on SimpleXMLElement instances, and should work on instances of stdClass.
More details can, probably, be found on the variable variables doc page.
