Asc Desc Table Headers

[nikko50]

Hello all.
I'm trying to figure out what the easiest way to have sortable table headers so when the users clicks the header it will sort ASC and then DESC if the same header is clicked again. The below is my code for the header so it will sort. Now how can I work in the ASC DESC part. Happy New Year to all.

<a class='sql2' href='$PHP_SELF?SORT=dayOff' >Employee</a>

You could use something like:

<a class='sql2' href='$PHP_SELF?SORT=dayOff&amp;desc=1' >Employee</a>
