Search and replace ought to be fine. Just remember that there are three-
types of shorttag:
<? ... ?>
<% ... %>
<?= ... ?>
The first two should be replaced with:
<?php ... ?>
The last one should be replaced with:
<?php echo ... ?>
The files you need to be careful with are XML files or PHP files that
generate XML output -- this is because '<?' is a commonly used construct
in XML to introduce a "processing instructions", such as an XML version
hint, or link to a CSS stylesheet or XSLT transformation.
Indeed, it's because of this '<?' confusion with XML that shorttag is
disabled by default in more recent versions of PHP. Careful authors can
author XML with PHP with shorttag enabled and not have any problems. But
not everyone is careful. ;-)
