Jeez, at least make a token effort. See the manual entry for ereg()? It
expects at least 2 parameters. Surely you can count past one? And surely the
error message is explicit enough?

No. But here's a snippet using preg_match():
$input_string = "#ircchannel";
if (preg_match("/^#[a-zA-Z]+/", $input_string) {
echo "Looks like an irc channel"; }
else {
echo "Go check your input";
}
What the above checks for is:
1) A line that begins with a hash (#)
2) Followed by one or more letters (non case-sensitive)
3) And nothing else
I don't know what letters/symbols/characters constitute a valid IRC channel so
you may have to season the above to taste.
