PHP flush

[n14charlie]

Hey

 

I need help using the PHP flush function.

I'm making a one time call to a php script and I want it to keep outputing stuff back to the client before it ends (inside a loop) I tried using the flush function but it doesn't work..

can anyone tell me how do I do that?

 

thank you

<?php
ob_start();
for ($i = 1; $i <= 10; $i++) {
sleep(1);
echo "$i<br />";
ob_flush();
flush();
}
?>

This works for me in Firefox 3.0.10 and IE8, but it depends on the server settings (and browser).

can you tell me what settings of the server should be set in order for it to work?

Have a read at http://dk2.php.net/manual/en/function.flush.php

yeah I just tested that script in Opera and doesn't work lol. Probably not Opera though, server settings I'm assuming like you said.

All of the web server, php, and browser compression, buffering, and minimum length block settings must must be satisfied, bypassed (flushed), or disabled.

 

If you are only going to be using this for yourself on your server, you have a chance of making it work. If you expect this to work once it is out of your hands, forget attempting to write an application this way, it is not how web servers and browsers were designed to work.

Well the thing is I'm writing an ajax application and I need it to check for online update every second, so my only other option is keep calling that PHP script again and again ..

so what would you guys recommend?

every second may be abit demanding on the server if there is alot of users on it at the sametime.
