Here the deal:
When the user closes the window, or presses the logout button, it will delete their (and only thier) username from the txt file. The reason I want to do that is so after the leave, it won't have their username on the User Window.
Here is chat.php
<?
$nickname = str_replace ("\n"," ", $nickname);
$nickname = str_replace ("<", " ", $nickname);
$nickname = str_replace (">", " ", $nickname);
$nickname = stripslashes ($nickname);
?>
&output=
<?
$chat_file = "chat.txt";
$chat_lenght = 40;
$max_single_msg_lenght = 100000;
$max_file_size = $chat_lenght * $max_single_msg_lenght;
$file_size= filesize($chat_file);
if ($file_size > $max_file_size) {
$lines = file($chat_file);
$a = count($lines);
$u = $a - $chat_lenght;
for($i = $a; $i >= $u ;$i--){
$msg_old = $lines[$i] . $msg_old;
}
$deleted = unlink($chat_file);
$fp = fopen($chat_file, "a+");
$fw = fwrite($fp, $msg_old);
fclose($fp);
}
$msg = str_replace ("\n"," ", $message);
$msg = stripslashes ($msg);
if ($msg != ""){
$fp = fopen($chat_file, "a+");
$fw = fwrite($fp, "$nickname : $msg\n");
$fw = fclose($fp);}
$lines = file($chat_file);
$a = count($lines);
$u = $a - $chat_lenght;
for($i = $a; $i >= $u ;$i--){
echo $lines[$i];
}
?>
