withou Reloading

[slice]

I am currently not able to figure out how it will be coded.
*Problem*
Main page where user will enter some data and click "calculation" button.And the page will be submitted to calculations.php .
calculations.php will output 10 results and usually takes 6 seconds for each result.In total it will take 60 seconds to calculate and show the results.

But i want to do some tricky work so that as soon as each result is calculated user should be able to see the result.But it should be without reloads of page.

I need your help to code this trick.
Thank You.

There is a function called flush() which pushes the current buffer to the browser. How ever you also may need to call ob_flush().

If you want to be able to manipulate the buffer output then look into the output control functions

http://uk2.php.net/manual/en/ref.outcontrol.php

[slice]

<?
echo("first <br>");
flush();
sleep(5);
echo("second <br>");
flush();
sleep(5);
echo("third");
?>

Its not working as intended

By default, output is sent to the browser as an when. If you want control over when it is sent you need to use ob_start() and ob_flush():

<?php
    ob_start();
    
    echo("first <br>");
    ob_flush();
    sleep(5); 
    
    echo("second <br>");
    ob_flush();
    sleep(5); 
     
    echo("third");
?>

[slice]

It's not working all the output is displayed after 10 seconds.Not as i want to do
First
then after 5 seconds
Second
then after 5 seconds
Third
In that way...

Which version of PHP are you using?

Also, look at this from the docs page:

we had problems with flushing data to the browser. a simple call to ob_flush() or flush() would not work. We found that repeatly calling theses fuctions did work however.

<?
flush();
ob_flush();
flush();
ob_flush();
flush();
ob_flush();
?>

go figure!

Not working

    ob_start();      
    echo("first <br>"); 
	flush();
ob_flush();
flush();
ob_flush();
flush();
ob_flush();
    sleep(5); 
     
    echo("second <br>"); 
	flush();
ob_flush();
flush();
ob_flush();
flush();
ob_flush();
    sleep(5); 
      
    echo("third"); 
?>

Php 4.3.10

Using the code I posted in #4, this is what I get.

Also, if you look at the code above, flush is only being used after ob_flush.

Its exactly working as i want.But what's problem with my code or php ?

Your web host may be buffering the reponse; this is all I can think of. Do you happen to know what web server they use?

I am testing it on my local host pc
