You can't do it directly in PHP as PHP is run on the server.

You could pop out some javascript that runs a countdown timer - you can google for a bucket of tutorials on that.

You could however possibly insert a row into a database with the start time and check it on a regular basis as scripts run - then display it one the next page that is loaded after the time has expired.

Edit: As Daniel correctly points out in the comment below (+1 btw) you could have a PHP file called by javascript that checks the database and pops out your message when the timer has expired.
