I think Rasmus summarized pretty well the essence of the initial decision that was made to include short tags. After getting all these precisions, I'm more inclined to the statut quo side, not that my opinion really matters, but I just feel there is no consensus right now and that this discussion runs into an obvious dead-end. What are we gaining by removing short tags ? Obviously nothing. What are we losing ? A lot of people demonstrated the usefulness, may it be limited, of the asp/short tags hence I feel we will lose something.
Purity in itself may be an argument, but not in a language that deems itself pragmatic. My 2 cents. On 4/14/07, Rasmus Lerdorf <[EMAIL PROTECTED]> wrote:

If you pick your standards carefully, sure. ;) I chose the PHP syntax before there was an XML spec. Back in the dark ages where HTML was defined as an SGML DTD. In SGML-speak <? is a general delimiter called PIO, < is STAGO and > is PIC. In those early HTML DTD's you couldn't have a PIO element that contained STAGO or PIC. ISO-8879 has all the uglyness in it if you want to dig a bit, but even with that it doesn't really tell the whole story of the conditions at the time. The point being that it was a conscious decision to not try to strictly comply with the specification at the time or to write a PHP DTD, but instead to focus on convenience first and the spec second. You still have plenty of things you can do today that doesn't match modern XML specs. For example: <?php echo '?>'; ?> Or anything with ctrl chars in it. You can put a literal 0x07 char in a quoted string, for example, and PHP will happily pass that through, but that is also not allowed in the spec. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
