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？

Question

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?

Answer 1

print "<textarea>" . htmlspecialchars($html) . "</textarea>";

Here you can find details about htmlspecialchars from official documentation.
