PHP Empty Object in Class

Question

Why is PHP Saying that my object is empty ?

Here is a simple use case.
It keeps returning the following error :

Fatal error: Cannot access empty property in C:\AdvancedApp\myApp.php on line 10.

class myClass
{
    public $myFunction = "Hello World";
}

$class = new myClass();

echo $class->$myFunction;

no more $ sign on the property when accessing it, just echo $class->myFunction; alone, by the way, that name is misleading — Kevin

The correct use of property is:

echo $class->myFunction;

What you did is used variable variables, the following will work:

$name = "myFunction" ;
echo $class->$name ;

Drop the $ sign from $myClass->$myFunction so it will be $myClass->myFunction, and what's with the variable name. Use something else, like myValue...
