R: difference between <?php and <?

if you know the xml language, you notice that all tags that start with <? are called processing-istructions tags, and the word that follow the question mark is the TARGET of the following istructions. This is an example of xml file: <?xml version="1.0"?> <?cocoon-process ....?> <?mypersonalprogram myistructions; ?> <?php myphpfunction(); ?> <tag>my text</tag> etc..... between <?php and <? there are no differences, but you should use the extended form (<?php) if you want that your code is more portable and reusable, in fact, you can't use <? alone in an xml file, the xml parser don't let you do that. -------------------------- Federico flagzenNO-SPAM@libero.it -------------------------- Php Guy <php_guy@ns.visors.com.hk> wrote in message Pine.LNX.4.21.0109100236160.2486-100000@ns.visors.com.hk... > Hi, > > I am a newbie at this PHP thing and I have been working from information > on the web and from books. > > I noticed that some start the PHP script with <? and some start with > <?php.
