我想在文本区域显示一个代码片段，以便轻松剪切和粘贴，如何？
问题描述：
I am generating a bit of code to display a picture as a link (frex <a href="site.com"><img src="/image.gif"></a>) I would like to show how it look, but also in a textbox adjacent show the actual code. Is there a function in PHP that will automagically escape HTML code so it can be displayed?
我生成一些代码来将图片显示为链接（frex ＆lt; a href = “site.com”＆gt;＆lt; img src =“/ image.gif”＆gt;＆lt; / a＆gt; code>）我想展示它的外观，还可以在相邻的文本框中显示实际代码。 PHP中是否有一个函数可以自动转义HTML代码以便显示它？ p>

print "<textarea>" . htmlspecialchars($html) . "</textarea>";
Here you can find details about htmlspecialchars from official documentation.
