Bill,
Sorry for not getting back sooner... had a lot of work interrupting my newsgroup time. :-)
Here-doc allows you to basically print out whatever is between the pattern you choose.
I use ENDOFHTML but you could use ENDOFCODE or whatever.
Perl has a similar construct:
print <<ENDOFHTML;
ENDOFHTML
Notice the semi-colon at the top, PHP is a bit more "correct" putting the semi-colon at
the end:
print <<<ENDOFHTML
ENDOFHTML;
PHP also uses "<<<" whereas Perl uses "<<".
Anyway, embedded PHP programs were the rave a couple of years ago, and people were doing
it trying to create really dynamic pages, but it's really messy as you've found out to
do it that way.
It's easier to print <<<EDNDOFHTML because you can actually use ' and "
in the block without trouble. There are also a lot of web servers that don't like embedded
PHP in HTML docs and will barf or ignore it if you attempt it. So, it's better to embed HTML in PHP,
and save yourself the hassle. One note, be careful about the placement at the end, the
end tag _must_ be over at the left, and no space after it, or it won't work.
