[PHP] The neverending Session

[Sean B.]

I'm working on a chat of sorts, and in the main frame that shows the actual 
messages, there is an infinite loop (while(1)) ... now, for whatever reason, 
when the browser is closed, the loop/thread/whatever just won't die. There 
are sessions involved, and the loop basically just checks a MySQL DB for new 
posts, and updates a timestamp in a user database. Any idea of why the 
loop/thread/whatever won't die?

Thanks,

Sean B.

Re: [PHP] syntax for session_register();

[Sean B.]

You were close: 
session_register("varname");
The key thing to remember is that it's the variable name WITHOUT the $. so...
$variable = "Hello";
session_register("variable");

[PHP] No output

[Sean B.]

I'm attempting to write a chat which streams HTML. There's a problem with the 
main function that's responsible for 'streaming'. It loops endlessly and if 
anytihng new appears in the database, it parses it into HTML and outputs it 
via the echo command. The chatboxDisplay method is what is responsible for 
parsing and echoing the message and the HTML for it. This is the problem 
code. The code is syntactically correct; it runs, in fact, if you remove the 
while stuff, it DOES work, except for the fact that it doesn't 'stream' like 
it should (Because it's not looping. It fires the output and the script 
ends). So when I put the while brackets back on to make it 'stream', there's 
no output. (as in, in netscape 4.7x it doesn't send much anything. the screen 
remains grey and just perpetually loads nothing) Any ideas as to what the 
heck is going on?

Thanks.

while (1) {

$posts=mysql_query("SELECT * FROM chat ORDER BY date DESC;") or die 
("Query failed line 111");
$data=mysql_fetch_array($posts);

while ($data=mysql_fetch_array($posts)) {
chatboxDisplay($data);
if ($data[id] > $id) { $id = $data[id]; }
}


flush();
sleep(2);


}
