Selective rendering of part of a page

[Paul E Collins]

I want to skip the rendering of certain parts of a Web page if the
user doesn't have a certain permission (e.g. a cookie). I'd like to do
it along these lines:

<p>Anybody can see this paragraph.</p>
<? start_protected _section($got_p ermission); ?>
<p>Not everybody can see this paragraph.</p>
<? end_protected_s ection(); ?>

Is it possible to disable the rendering of a section outside the code
like this (perhaps by setting a PHP flag to redirect subsequent
output)? I don't really want to complicate things by moving part of
the page into a separate "include file" or mixing the HTML and PHP by
using a here-document (the <<<END syntax).

Eq.

<?php
if($condition){
?>
protected html here
<?php
}
?>

Mostly HTML, few PHP. Enclose the PHP code between <? ?:

<p>Anybody can see this paragraph.</p>

<? if( $got_permission ){ ?>

<p>Not everybody can see this paragraph.</p>

<? } ?>

Go and download a template engine like Smarty

http://smarty.php.net/

and separate your code from your layout. I use it for quite some time
and maintainability of code is much better.
