    }
}
ab::asd();

i want to find a way to point to a class static member .like the example above,how can i make this work?

Answer 1

If you access a static variable, the syntax is the following:

MyClass::$variable

So what you’re doing lacks the indirection:

echo self::$$a;  //output 34;

This works with regular variables the same way:

$variable

and with indirection:

$name = "variable";
$$name

An advice for your next question: Try to be more precise in your question. Pay attention to the following:

• What you have
• What it should do
• What actually does
• Where the error occurs if you know

This helps to give relevant answers more quickly instead of engaging in a meta-discussion to clarify your question.
