EU tripod may allow you to host PHP for free, but it also puts ads on the page. They way they do this is by executing additional code once the page has completed. However, if the page ends in a parse error, or any fatal error, it will not be able to execute. So the solution is simple. At the bottom of your code, or footer php, add the following.
<div style="display: none;"> <? no_more_ads();
because the function no_more_ads() does not exist, the ads will not appear! It will however add an error message to the bottom of your page, which is what the hidden div is for.
