Output Problem

This is example

Now the output when i can it from database table my_code will appears as code

This is example

While i want it appears normally as visual HTML (applied) as following

This is example

Note : someone said rather than rendering html code in the input text just put it as it < and > and yes it would appears in output just as i want but when i try to edit it in edit page will find a huge distortion where it become active as textarea inside textarea so i must rendering it but in same time i want it appears as i want.

Yes. Then only apply the HTML escaping (htmlspecialchars) when you want to edit your content.

If you want to output it as raw HTML (meaning it becomes a functional <textarea>+text), then do not apply said HTML escaping.

You cannot use the same htmlescaped data for both purposes. You have to apply it depending on what you want to do with it, and best only right before you do so.

Fine, I understood your idea and by using htmlspecialchars for example <?php $new = htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES); echo $new; // <a href='test'>Test</a> ?> Now is there any thing that can convert <a href='test'>Test</a> back to <a href='test'>Test</a>
