在PHP中的PHP变量没有其他方式：<？php echo $ var; ？> [英] php variable in html no other way than: <?php echo $var; ?>

问题描述

我在混合的HTML和PHP中工作很多，大部分时间我只想要带有几个PHP变量的纯HTML，所以我的代码如下所示：

I work a lot in mixed HTML and PHP and most time I just want solid HTML with a few PHP variables in it so my code look like this:

<tr><td> <input type="hidden" name="type" value="<?php echo $var; ?>" ></td></tr>

这非常难看。

Which is quite ugly. Isn't there something shorter, more like the following?

<tr><td> <input type="hidden" name="type" value="$$var" ></td></tr>

这是可能的，但您会遇到（你必须全部用'<<$ code>替换它们）并且布局不见了



This is possible to but you get stuck with the "" (you have to replace them all with '') and the layout is gone

echo "<tr><td> <input type="hidden" name="type" value="$var" ></td></tr>"

有没有更好的办法？

Is there anything better?

推荐答案

<tr><td> <input type="hidden" name="type" value="<?= $var ?>" ></td></tr>

哪些（在PHP 5.4之前）需要在PHP配置中启用短标签。它的功能与您输入的代码完全相同;这些行在其内部实现方面的字面意思相同：

which (prior to PHP 5.4) requires short tags be enabled in your php configuration. It functions exactly as the code you typed; these lines are literally identical in their internal implementation:

<?= $var1, $var2 ?>
<?php echo $var1, $var2 ?>

这就是内置解决方案。有很多第三方模板库可以让您更容易地在输出中嵌入数据， smarty 是一个好地方开始。

That's about it for built-in solutions. There are plenty of 3rd party template libraries that make it easier to embed data in your output, smarty is a good place to start.
