This is always a source of confusion. http://www.bin-co.com/php/articles/using_php_short_tags.php <?= $foo ?> is generally NOT what the short tags controversy are about. It's the use of <? Some php here ?> vs. <?php some php here ?> While it is true that the 'short_open_tag' directive enables both (for some stupid reason), the issue is that it's poor form to use JUST <? And not <?php just as it's a bad idea to use <% %> (asp tags). Using <?= is perfectly fine and in my personal and professional opinion, preferred to the uglier <?php echo $foo; ?> way This topic was very heated when the core PHP developers were going to remove the <? Form all together in future PHP 6 versions and everyone got their panties in a bunch because they assumed it meant the <?= form too (which it did not). http://php.net/manual/en/ini.core.php http://www.php.net/~derick/meeting-notes.html#remove-support-for-and-script- language-php-and-add-php-var -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
