Rahul,
You need to flush() your output. But beware - just because it goes to
the browser doesn't mean the browser will display it. For instance, if
it's in a table, the browser may wait for the entire table to be sent.
And there are a lot of other possibilities.
But if you keep it short and clean, you have a better chance to get your
message displayed immediately.
