把上面的代码复制到当前主题的 functions.php 文件或者直接保存插件上传之后，就可以在 Widget 标题输入类似的代码：“测试粗体和斜体”实现粗体和斜体的 HTML 标签。上面的代码让 Widget 标题仅仅支持加粗和斜体两种 HTML 标签，但是我们可以通过相同的方法非常容易自己添加其他的 HTML 标签支持。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
如果是普通的php中想让标题支持html标签可以使用如下的代码</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode15" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<br>
$title = str_replace( '<', '&lt;', $title);<br>
$title = str_replace( '>', '&gt;', $title);<br>
$title = cn_substr($title,80);</div>
