我想在文本区域中显示一个代码片段，以便可以轻松地剪切和粘贴它，怎么办？
[英]I would like to display a code snippet in a text area so it can easily be cut and pasted, how?
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. 
我正在生成一些代码以将图片显示为链接（frex <a href="site.com"><img src="/image.gif"></a> ），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。 Is there a function in PHP that will automagically escape HTML code so it can be displayed? PHP中是否有一个可以自动转义HTML代码以便可以显示的函数？
