在PHP中将字符串拆分为多个部分

Question

I'm writing an IRC bot in PHP and trying to split the below notice down in to multiple parts.

:irc.server.com NOTICE PHPServ :*** CONNECT: Client connecting on port 6667 (class users): Guest!Guest@127.0.0.1 (127.0.0.1) [Guest]<br />

So far I am using:

while(1) {
    while($data = fgets($socket)) {
        echo nl2br($data);
        flush();

        $ex = explode(' ', $data);

        if($ex[0] == "PING"){

            fputs($socket, "PONG ".$ex[1]."
");

        }

        if($ex[1] == "NOTICE"){
            if($ex[6] == "connecting"){

            $userstring = $ex[12];
            $usernick = strstr($userstring, '!', true);
            $userip = strstr($userstring, '@');

            }
        }
    }
}
?>

So $user.nick is working ok but $user.ip includes the @ and the IP address. Why does this include the @ but the nickname doesn't include the !?

Also how can I get $user.ident which is between the ! and the @?

Answer 1

try:

$userParts = explode('@', $userstring);
$userip = end($userParts);
