As many others have said, htmlentities()will do the trick... but it will look like shit.
正如许多其他人所说，htmlentities()会成功……但它看起来很糟糕。
Wrap it up with a <pre>tag and you'll preserve your indentation.
用一个<pre>标签把它包起来，你会保留你的缩进。
echo '<pre>';
echo htmlspecialchars($YOUR_HTML);
echo '</pre>';

You should use htmlspecialchars. It replaces characters as below:
你应该使用htmlspecialchars. 它替换字符如下：
- '&' (ampersand) becomes
& - '"' (double quote) becomes
"when ENT_NOQUOTES is not set. - "'" (single quote) becomes
'only when ENT_QUOTES is set. - '<' (less than) becomes
< - '>' (greater than) becomes
>
- '&'（与号）变成
& - '"'（双引号）
"在未设置 ENT_NOQUOTES 时变为。 - “'”（单引号）
'仅在设置了 ENT_QUOTES 时才变为。 - '<'（小于）变成
< - '>'（大于）变成
>

To display HTML tags within a browser, surround the output with < xmp> and < / xmp> tags
要在浏览器中显示 HTML 标签，请使用 <xmp> 和 </xmp> 标签将输出括起来

You can use htmlentities when echoing to the browser, this will show the tag rather than have html interpret it.
您可以在回显到浏览器时使用 htmlentities，这将显示标签而不是让 html 解释它。

There is another way...
还有一种方法...
header('Content-Type: text/plain; charset=utf-8');
This makes the whole page served as plain text... better is htmlspecialchars...
这使得整个页面作为纯文本......更好的是htmlspecialchars......
Hope this helps...
