自动刷新php循环计数器的ajax显示

Question

I'm been around php for a few months, but am new to ajax. At this point, I've been able to use ajax to launch my php script and update my page results without reload and i've been able to auto refresh another script to run it more than once.

I have large recordsets that can take 8 - 10 - 12 minutes to process depending on what's being done. I'd like to be able to auto refresh an ajax "progress" display on my page that says "Processing record x of y" where x is the loop counter and y is the number of records in my recordset and both are php variables.

I've searched, but don't seem to find anything like this. Can anyone help point me in the right direction?

Thanks

What you can do is while the first ajax is still in progress and php script runs update either a database record or a session variable with the progress. Then have periodic ajax requests ( other ajax requests apart from the main ajax request) that grab the progress from either the database record or session variable and send the progress back to the client, this progress can then be displayed. Keep doing this until the main ajax request has finished.
