tooltip for link

I am trying to make a kind of tips for each link i have in the table . I mean that i have a table with 2 cols , one for displaying lists of links while the other is for displaying the tip of that link ( in multi lines - i use <textarea> not <input type=text>) i want when the user move the mouse over a link on the left , the tip of that link will be displayed on the right . The problem is that i can't make it with javascript , so i think it will be solved in PHP .
Anyone ever done this before ? Please show me how you have made it .

1) Why can't you do it in JavaScript?

2) That would be impossible for PHP. PHP is a server-side language. Your task would require a client-side language. It's simply, straight to the point, no workarounds, impossible.

You need a client-side language to do that. To do it in PHP would require requesting a new page from the server for each tooltip, which kind of defeats the purpose of a mouseover tooltip
