I don't know much about PHP, nor do I understand exactly what your problem is, but since PHP files usually are saved as .php, I am wondering if naming your file file.txt instead of file.php might be the problem.

You might also want to look at your HTML and consider an external CSS vs. inline styling and avoid the deprecated tags you are using.
