Variable function name within a class

[ozben]

I have declared a function "foo" within a class and I want to call it within the class via a variable function name like this:

$function_name = '$this->foo' ;
$function_name() ;

But this syntax gives the error:

Call to undefined function: $this->foo()

If I call the function $this->foo() directly it works fine.

Can someone please tell me how to define a string that will refer to a function within a class?

TIA.

Try:

$function_name = 'foo';
$this->$function_name();
