文章标签： php echo html页面

这篇博客介绍了在PHP中如何输出HTML，包括在PHP标签间直接写HTML，使用echo和条件语句，heredocs和nowdocs等方法。同时，讨论了PHP作为模板引擎的原始用途，特别是短标签的使用。文章强调了使用模板引擎如Smarty、Twig等带来的好处，主要是分离设计逻辑和业务逻辑，使代码更清晰、易于维护。最后，指出尽管PHP支持短标签，但因配置依赖性，不推荐广泛使用。

There are a few ways to echo HTML in PHP.

1. In between PHP tags

2. In an echo

if(condition){

echo "HTML here";

}

With echos, if you wish to use double quotes in your HTML you must use single quote echos like so:

echo '';

Or you can escape them like so:

echo "";

3. Heredocs

4. Nowdocs (as of PHP 5.3.0)

Template engines are used for using PHP in documents that contain mostly HTML. In fact, PHP's original purpose was to be a templating language. That's why with PHP you can use things like short tags to echo variables (e.g. =$someVariable?>).

There are other template engines (such as Smarty, Twig, etc.) that make the syntax even more concise (e.g. {{someVariable}}).

The primary benefit of using a template engine is keeping the design (presentation logic) separate from the coding (business logic). It also makes the code cleaner and easier to maintain in the long run.

If you have any more questions feel free to leave a comment.

Further reading is available on these things in the PHP documentation.

NOTE: PHP short tags and ?> are discouraged because they are only available if enabled with short_open_tag php.ini configuration file directive, or if PHP was configured with the --enable-short-tags option. They are available, regardless of settings from 5.4 onwards.
