PHP parse error after upgrade

Greetings!

While doing a web server upgrade, I also decided to upgrade PHP from
4.4.4 to 5.2.5. After putting the new server in a test environment (actually
just listening on a different port and using the same DocumentRoot), one
PHP script fails with a message like this:

PHP Parse error: syntax error, unexpected ';' in
/apps/httpd/data/admissions/pagemaker.php on line 48

Here is a snippet of the script that failed:

if ($navtable == 'about'){
echo ?> }elseif ($navtable == 'student'){
echo ?> }elseif ($navtable == 'staff'){
echo ?> }elseif ($navtable == 'visit'){
echo ?> }elseif ($navtable == 'apply'){
echo ?> }elseif ($navtable == 'links'){
echo ?> }elseif ($navtable == 'recruit'){
echo ?>
}elseif ($navtable == 'international'){
echo ?> }else{
echo 'Please call 827-6414 to report a problem on this page';
}
?>

Line 48 is the one that says
echo ?>
This script does not generate any errors under 4.4.4. I did look at the
4 to 5 compatibility guide on the php.net site but I didn't see anything
that would explain this. Can someone give me a hint as to why this no longer
work under version 5? Thanks!

*ahem*. What are you echo()ing, again?

I'm guessing that in PHP4 a "?>" implied a ";". It still does, but if the
start and end tags are in the same line, and there is just one sentence in
between.

Just a guess - grab a copy of the parser's source code and its grammar if
you really want to be sure. In the meantime, please fix your empty
echo()es.

Uh ... ugly, buggy and unreliable. What about replacing this mess with
something like this:

$pages = array('about', 'student', 'staff', ...);
if (in_array($navtable, $pages)) {
include "{$navtable}navtable.inc";
} else {
echo 'Please call 827-6414 to report a problem on this page';
}
?>
