What should process the data if there is no target? The assumption of PHP when no target is declared is not part of the standard. Just because you've done two anecdotal enterprise projects and haven't had a problem, doesn't make it right.

I spoke too fast, I thought we were talking about <? and not <?= The latter is questionable since technically the = could be considered a processing character (at least from what I read in the spec. Perhaps it is ambiguous though with other languages.

And on further reading I'm pretty sure the = character does not fall into the allowed caracters for a PITarget: http://www.w3.org/TR/REC-xml/#NT-PITarget Cheers, Rob. -- E-Mail Disclaimer: Information contained in this message and any attached documents is considered confidential and legally protected.

I am sure you will find programmers on both sides and in the middle of this argument. Some saying they never use it, others saying that they always use it, and still others saying "It depends" -- meaning they use it in certain cases. I believe, just because it can be done doesn't mean that it should be done. My practice is *never* to use <?= In fact, my practice is to not only use <?php echo, but to enclose the echo argument with a (), like: <?php echo("The answer is $answer");?> I am sure there will be some that think that my practice is an overkill, or not "good practice", but it's a good thing that we all have a choice. Make your choice to best serve how you want your code to look. Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com |
