How to access a memer variable a with symbol

问题

I have a property of a PHP stdClass which starts with an @ symbol (according to my debugger). How do I access its value?

@averageBaseRate = "22.49"

回答1:

Use curly braces:

$obj->{'@averageBaseRate'}

It's the complex (curly) syntax applied to an object.

Using that syntax, you can use any name you want for the member variable.
One can even put really strange Unicode characters in the name.
