The last thing my instant messaging program needs to do is refresh if someone someone types something in. i thought that a way to do this is to have an enless loop. so When a file size is changed echo my text.
<?php
$filename = "am.txt";
$size = filesize( $filename );;
while ($size = $size)
if ($size !== filesize( "am.txt" ))
{

echo "tHE FILES ARE NOT EQUAL SIZE. YOU HAVE DONE IT!!!";
}
?>
That doesnt work. How can i edit it so that it will, and when the filesize changes echo my text?

I take it the deletion of the previous topic means that you got the nl2br() function to work as you wanted it to.

If this is an instant messaging program, it's pointless having an endless loop, as the data is not sent to the client until the page has finished output.

What you should consider doing, as I assume this is a javascript based chat client (although it can be done with plain HTML) is to call the filesize (well, when I made one, I called the MD5 of the file, as with filesize cheese and ceeehs will give the same filesize, and not update) into the script and check it there, THEN refresh the page.

Erm, you're probably wondering what the hell I'm on about, and if thats the case, disregard the above 😛

md5 is a hash. What is cheese? and ceeehs. I asked my good buddy google.com. And even he didnt know. (i thought he knew everything). So what is it, or where can i learn about it? the messenger work right now, exept i just had it refresh the text frame with meta refresh tag. And that works fine. But i think it would be better to have it only update when it is needed to be. So where can i learn about those.

Lol, I'm just saying that if you have the file with the word "cheese" in it (one message) and then the next person overwrites it with the word "ceeehs" then it'll have the same filesize.

Unless you're downloading the entire messages each time, which after a little while would become really slow.

I just took a look at the code that I wrote a while ago for the chat script I made. It's a mess. It had /search SOMETHING and you it'd do an MSN search. That was so cool...
