I ran into an issue with a heredoc that works in Perl, but apparently not in
PHP. I want to write the output of the heredoc to a file other than stdin,
which is done in Perl as:

print fOutput <<EOF ;
My Text
My HTML
EOF

and you can use

print <<EOF ;
...
EOF

for output (echo) to stdin.

But in PHP it is either:

print <<<EOF
...
EOF;

or

echo <<<EOF
...
EOF;

And there seems to be no way to do this. There is also a bug report/request
on the subtle behavior of the heredoc regarding whitespace:
http://bugs.php.net/bug.php?id=24750

But I found something called a nowdoc which might allow this:

$str = <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
EOD;
fwrite( $fh, $str );

http://www.php.net/manual/en/language.types.string.php#language.types.strin g.syntax.heredoc

OK, that works. I have changed the subject to reflect it has been solved.
This is still a good reference for other newbies and Perlites.

I also tried using $stdout but it did not work, although the following seems
to hint that it might:
