You have this tagged as PHP, but this sounds more like a job for JavaScript. The Search module is already preventing empty searches, which is why you get that error page. Lots of ways to accomplish this, here is one way if you are using jQuery:

$(document).ready(function() {
    $('#search').submit(function() {    
        if ($('#keywords').val() == '') {
            return false;
        }
    });
});
