Is there any way to get the following snippet returning a true? ... $this->var = ????? if ($this->var == $preDefinedStringToTestWith)
     return true;
else
     false;
The problem: I don't know, what $preDefinedStringToTestWith is! $this->var can be set to any string. I tried $this->var = "${preDefinedStringToTestWith}" but this doesn't get expanded.
Uh! Shouldn't it work? $this->var = $preDefinedStringToTestWith

For certain reason $this->var can only be set to a string and not to a variable! Any suggestions?
