Some simple question

[abdfahim]

I have a php code which calculate different formula from different mysql database and insert the results in another database. Formulas are really nasty and it took about 30 minutes to execute the full code. Now, After calculating each formula (there are about 400), I insert the result in database and echo a simple line. I want these lines to be displayed progressively (so that I can trace the progress), but it execute whole script first and then show the 400 lines simultaneously. Is there any way? My code is like

 

(for i=0;i<400;i++){
    Calculate formula
    Insert into Database
    echo sample line
}

Use flush() after the echo.
