How to get menu for special characters in PHP?

No, of course it won't work in PHP code. What you're trying to do is to create an HTML character entity. If you want to use HTML code, switch out of PHP.

It sounds as though you are trying to use echo to display your text. When you create a string in PHP code, Dreamweaver treats it as literal text. It has no way of knowing you're trying to insert HTML.

I've just taken a look at your website. Snæfellsnes is displayed correctly:

If you're seeing SnĦfellsness, it means that there's an encoding conflict. UTF-8 characters are being rendered as ISO-8859-1 (Western European). All browsers now support UTF-8, so there's no reason to be using Western European as your encoding.
