I would like to display a code snippet in a text area so it can easily be cut and pasted, how?

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>";

在这里，您可以从官方文档中找到有关htmlspecialchars的详细信息。

Answer 2

htmlentities()
