Description: infinite loops prevents pages from loading

I have tried a meta tag, but the screen flashes when the page is refreshed.

In addition to my previous postings, when I open two browser windows by clicking on their icons and write the address in the address box, the script works, when I press the ctrl-n keys and open a new browser window the script freezes.

Thank you,

Argun

This sounds like an unreliable way to accomplish your goal, as you are finding out.

Don't you think it would be better to simply have a META tag refresh the chat session (could be a frame or what not) every X seconds? Could have the user list in a seperate frame and the message entry area in another.

This is going to be used for a chat board, there will be an infinite loop which reads from a mySQL db and flushes the output.

I tought there was something wrong with my db access code however I realised that, the code was not working altough I have simplified it as I have posted.

I have tried with different os and web server software. I have tried Linux & Apache and Win2k & IIS5.

When I open the page, it works fine. When I open the same page in another window at the same computer it still works fine however if I try to open a third browser window (private chat with 3 person for instance) the browser window freezes and if I close one of the previous browser windows the third window starts working.

Thank you,

1.) Why are you doing an infinite loop in the first place?

2.) This is working just fine for me on my linux machine with 4.0.5.

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1254">
<title>Loop</title>
</head>
<body>
<?
for($value=1; $value>0; $value++){
        echo"<br>$value";
        
        flush();
        sleep(1);
}
?>
</body>

</html>

The code above does not work when opened in more than two browsers on the same computer.

Any ideas?

Thank you.
