Calling a class's constant in another class's variable

Question

I was wondering if there is any possibility in PHP to do following;

<?php

class boo {
 static public $myVariable;

 public function __construct ($variable) {
   self::$myVariable = $variable;
 }
}

class foo {
  public $firstVar;
  public $secondVar;
  public $anotherClass;

 public function __construct($configArray) {
   $this->firstVar = $configArray['firstVal'];
   $this->secondVar= $configArray['secondVar'];
   $this->anotherClass= new boo($configArray['thirdVal']);
 }
}

$classFoo = new foo (array('firstVal'=>'1st Value', 'secondVar'=>'2nd Value', 'thirdVal'=>'Hello World',));

echo $classFoo->anotherClass::$myVariable;
?>

Expected OUTPUT : Hello World

I am getting following error; Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM

I Googled and it is related to colon (double dots) in $classFoo->anotherClass::$myVariable

I wouldn't like to go all the trouble to change my other classes. Is there anyway around this problem?

Thank you for your help in advance.

P.S. I just didn't want to lose few hours on this to find a way around. I already spent yesterday 2.5 hours to change almost whole Jquery because customer wanted a change and today in the morning I was asked to take the changes back because they didn't want to use it (they changed their mind). I am just trying to avoid big changes right now.

You need to do:

$anotherClass = $classFoo->anotherClass;
echo $anotherClass::$myVariable;

Expanding expressions to class names/objects for static calls/constants is not supported (but expanding variables, as shown above, is).
