Buffered page rendering

[Anon]

Hello,

I'm generating an HTML page from a SQL query that may take up to 20 seconds to display. During this time, the user is seeing a boring blank page.

How may I make the browser to display right away some page header, then finish displaying the page when the SQL query completed ? Do I need to use PHP4 output buffering functions (ob_...) or do I need to play with HTTP redirection ?

A code snippet or some hints will be helpful.

Regards,
Jeff.

1. Be sure to lay out your page so that the top portion is a discrete table and is closed off before you do the sql query. Netscape won't draw tables until they are complete.

2. flush().
