PHP - IRC Bot Not sending message Help

Question

Currently I am making a IRC that sends a message onto the IRC main channel. Here is my code:

Answer 1

fwrite($ircSocket, "PRIVMSG " . $ircChannel . " " . $msg = $_GET['msg'] . "\n");

To:

fwrite($ircSocket, "PRIVMSG " . $ircChannel . " " .$msg. "\n");

Answer 2

Change:

$msg = $_GET['msg'];
...
fwrite($ircSocket, "PRIVMSG " . $channel . " :" . $msg = $_GET['msg'] . "\n");

To:

$msg = $_POST['msg'];
...
fwrite($ircSocket, "PRIVMSG " . $ircChannel . " :" . $msg . "\n");
