is there a way to send info to a browser during a loop?

Can I do that like this?:

 

<?php

for($i=0;$i<=10;$i++){

echo 'this is something '.$i;

}

//some more php code would go here before the entire script is finished executing.

?>

Only works on some browsers

 

<?php
for($i=0;$i<=10;$i++){
    echo 'this is something '.$i;
    ob_flush();
    flush();
}
?>

 

ob_flush and flush

yep I tried that too. It didn't work...I am using firefox, would that be why?

Well a loop of 10 would not really show this. It works in Firefox cause that is what I use and I know it works...try this.

 

<?php
set_time_limit(100);
for($i=0;$i<=10;$i++){
    echo 'this is something '.$i;
    ob_flush();
    flush();
    sleep(5);
}
?>

 

It should take display that every 5 seconds.

 

Along with the browser difference, I know that some Anti-virus software will hold your page buffer until the end then display it, so that is also something to think about/check.

Php, different web servers and different web server settings for buffering and compression, and different browsers and different browser settings for compression affect if and when you can incrementally send output from a server to a browser.

 

You should not expect a web based application to be able to do this from the server side. If you get it working on one setup, it probably won't work on the next.

 

To get a value to update in the browser, you should have the browser get that value from the server using AJAX.
