First of all, take a look at the polyline example:
http://code.google.com/apis/maps/documentation/javascript/examples/polyline-simple.html
Without seeing your complete code, you shouldn't be calling document.write.
Your code should look something like... (fill in the blanks)
var map = new google.maps.Map(...
var gliderPath = new google.maps.Polyline({
map: map,
path: route,
strokeColor: "#ff0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
Of course, insert this code after your generated "route" array from php is
in scope
