Storing files as, well, files is never a good idea, if stored as PHP files and then include/require(ed) the scripts could contain malicious code. There are two options;
1,
Save the file as .htm, .html, .txt (or some other plain text format)
Include the file with
<?php
echo file_get_contents($FileToGet);
?>
This will get the contents of the text file and echo it to the browser without executing any code inside.
2,
BLOB!
There is a field type in MySQL called BLOB (Binary Large Object) which I use for storing my files, it can hold a large amount of data, all you have to do is output it as you would with any other MySQL field
