推荐答案

通常，您像这样编写PHP:<?php PHP CODE HERE ?>.但是，如果启用了 allow_short_tags 指令，则可以使用:<? PHP CODE HERE ?>.另外，sort标签还提供了额外的语法:<?= $var ?>等于<?php echo $var ?>.

Normally you write PHP like so: <?php PHP CODE HERE ?>. However if allow_short_tags directive is enabled you're able to use: <? PHP CODE HERE ?>. Also sort tags provides extra syntax: <?= $var ?> which is equal to <?php echo $var ?>.

短标签似乎很酷，但事实并非如此.它们只会引起更多的问题.哦，还有IIRC，它们将从PHP6中删除.

Short tags might seem cool but they're not. They causes only more problems. Oh... and IIRC they'll be removed from PHP6.
