How can I access my classe's var inside the class?

Question

I have a class:

class MyClass {
    public $a = 'blablabla';
}

And I want to access the variable $a inside the class without needing to use any function, like

class MyClass {
    public $a = 'blablabla';
    public $b = $a;
}

I tried using public $b = $this->a , public $b = MyClass->a , and many other alternative ways to try to do what I want, and nothing. And I didn't find anything on Google that could explain what I want.

Could someone please help me? Thanks.

I am not sure why a simple variable call will not work, but you can try:

 class MyClass {
  public $a = 'blablabla';

   function geta(){
   return $this->a;
    }
   $b=geta();
}
