i'm trying to make a chat room script it's almost done but right now i'm making some irc commands. how can i make it so thhat if someone types /me blah then it will display something else?

You could use regular expressions to do pattern matching and string replacement. I am assuming that you'd want to replace "/me" with the user's name?

Try this:

//Example 1
// replace ALL instances of "/me"
$message = preg_replace("/\/me/", $user_name, $message);

//Example 2
// replace only instances at the beginning of the string
$message = preg_replace("/^\/me/", $user_name, $message);

//Example 3
// replace case variations, i.e. "/Me", "/ME", & "/mE"
$message = preg_replace("/^\/me/i", $user_name, $message);

Not exactly. If someone types:

/me falls down

Then I want it to make it into:

[$Time] $Username falls down

If you could give us the code relevant to this, it would be a lot easier helping you. //Daniel

Forgive me, Aren't chat room scripts real time and therefore unable to be run effectively as they require constant updates?

PHP is server side so you'd have to keep refreshing your browser window.

Normally this sort of thing would be done in java. ***************************************

Well, just use the line of code that behaves as you want (I'd recommend #3, but I listed the others as examples), and replace:

$user_name

- with -

"[".$Time."] ".$Username

Did you look over the manual pages I listed? They'll be great help.
