Subject: [PHP] Expand variable in comparison

Hi!


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?
