在WordPress中使用文字实体
使用文字实体是设计中一个有趣的部分！你可以在模板标签中使用这些特殊符号，如the_category()标签。注意：the_category() 模板标签列表，在文章meta数据 部分，多种分类指定为文章。
In this example, the special character entity, the heart (♥) symbol, separates the categories of WordPress, Computers, and Internet News:
<?php the_category(' ♥ ') ?>
在这个例子中，特殊的文字实体心形(♥)符号把WordPress, 电脑和网络新闻 分类分开来：
<?php the_category(' ♥ ') ?>
In this example you see the use of an accent in your post's title:
<?php the_title('∞ ', ' ∞'); ?>
这个离子中你可以看到文章标题中使用的其中一种符号：
<?php the_title('∞ ', ' ∞'); ?>
If you want to highlight the post's author, you don't have to use a character entity inside of a WordPress template tag. You can use it in the text.
<div id="author">♦ <?php the_author(); ?></div>
如果你想要把文章作者高亮显示，你不用在WordPress模板标签中使用文字实体，你可以使用以下代码：
<div id="author">♦ <?php the_author(); ?></div>
As you have seen, there are a many uses for character entities within your site. With this information you can experiment and find creative ways to use these symbols in your design!
- Note: Not all template tags can use character entities, especially those tags that use boolean parameters. Test a template tag thoroughly to be sure that it will accept the symbols.
如同你所看到的，在你的站点中有很多文字实体的使用。你可以实验，然后找到更多创造性的方法来使用这些符号做好你的设计！
