I'm going through a book for the second time and I got the following error message for the following script.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
" xml: lang="en" lang = "en">
<meta http-equiv = "content-type"
content = "text/html; charset=utf-8" />
<p>Today’s date (according to this web server is
echo date('l, F dS Y.');
FWIW last time I did this I used an actual server on a site and I'm assuming it could have been set not to display errors.
