First thing i notice, you got this off of a tutorial, as i got my first bot of there, and the problem is it\'ll only get the first 128 characters, to fix it change

while($data = fgets($socket, 128)) {

to

while($data = fgets($socket)) {

secondly i\'d do like a server function... something like

function send ($action, $channel, $extra, $message) {
if (isset($extra)) { fputs($socket, $action $channel $extra .\":\".$message.\"\\n\"); }
else { fputs($socket, $action $channel .\":\".$message.\"\\n\"); }
}

then that way all you have to do is send(\"MODE\",$ex[2],\"+o\",$ex[4]); or stuff like that :)

Thirdly, you have an extra closing bracket on the end :)

Fourthly, It isn\'t exactly a \"PHP to IRC\" it is a \"PHP IRC Bot\". When i saw \"PHP to IRC\" i thought it was a IRCd Scripted in PHP. But its only a PHP IRC Bot :) so perhaps you\'d like to change the title?

Besides that, good job.
