is "EOFORMPAGE" simply not used?

Hi,

I'm developing a website in PHP - it's my first one... :-)
Somewhere (I'm not sure where) I've come up with the function:
"EOFORMPAGE". I use it like this:

$content = <<< EOFORMPAGE
<table border=1>
<tr>
<td><b>test</b></td><td>$test</td>
</tr>
</table>
EOFORMPAGE;

This enables me to use straigt HTML, put in in a variable ($content in
this case), and add the content of the variable $test in this case as
well. This works very good. It is especcially usefull when working
with JS, as I'm not limited by problems with quotes.

My concern: I cannot find another example of this function
"EOFORMPAGE" /at all/. Is it not used? Frowned upon? Depricated? Can
someone help me out on this one, as I would not like to write code
that is considered 'bad'.

thanks,

Paul
