The error is not related to PHP version, MySQL version, your OS or
(PHP errors never are) to the browser. The problem is probably
related to your PHP settings. In the first case (when the script
works) you have short tags turned on, and in the second case
you have short tag turned off.
Read about "short_open_tag" setting in "php.ini" (or --enable-short-tags
configuration directive).
In general usage of short tags is discouraged because it makes
your script less portable (it will not work with short tags turned
off).
Change this:
b = <?=$rec?>;
to this:
b = <?php echo $rec; ?>
and the script will work regardless of short tags being on or off.
(Also do not use "<?" instead of "<?php" - it's also a short tag,
not only "<?=").
