PHP does not have an alert box identical to JS, but you can construct a box just like that (using CSS) in PHP and display that on the screen.

You could go another way. Output the alert text to an html element with a certain class or id and then check with javascript if the element has content and if it has display an alert.

For the example i will use jquery to code the javascript side.

[PHP]
if($var == 'bad'){
echo '<p id="error">You made a bad move</p>';
}
[/PHP]

$(function(){
    var error =  $('#error').text();
    if(error.length > 0){ alert(error); }
});

IMHO on the javascript side there are nicer solutions then an alert box.
