HTML code inside PHP code

Hey! I need help before I explode because of frustration.

I am using the plugin “Allow PHP in Posts and Pages” –
And I want to echo out the HTML code inside my PHP code but it doesn’t react..
I’ll give you an example:

[php]$numb = 1;
switch ($numb){
case 1:
echo ‘<a href="url">Link text</a>‘;
break;
default:
echo “Something went wrong! Please contact admin!”;
}[/php]

But it doesnt respond as html text – the output is just plain text: “Link text”..

How can I solve this? I tried to..
echo ‘[/php]<a href="url">Link text</a>[php]‘;
But I reed that everything needs to be within the [php]&[/php]

Thank you for further help!
