You appear to be looking for the eval function: http://php.net/eval
However, in 99.99% of cases using eval is not the right solution. In
your case there are two ways to solve it.
The first way, assuming the thing you're trying to include is a
stylesheet, is to use an external link to a CSS file. That would be
the "normal" way to include a stylesheet in an HTML page and is far
more efficient that including it inline.
If it's not just a stylesheet that you're including then you'll want
to load the file in the getTop method. For example...
$toReturn = "<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0
Transitional//EN' ........";
$toReturn.= file_get_contents('styles3.txt');
$toReturn.= '..........';
Simple as that.
