Thanks for the function btw, its been really useful, one small tweak though….

instead of
‘/’.$ipregex.’/’

should be:
‘/^’.$ipregex.’/’

Only because if an allowed IP was
$ip[] = ”211.*.*.*”;

it would also allow an IP of 74.192.211.23

thank you. I was trying to make this on my own when I came across yours. Why do more work :) Very nice, short, and simple.

Thanks for this function. There is small bug in it. You are missing backslash in preg_replace.

Should be like this:

$ipregex = preg_replace(“/\./”, “\.”, $ip[$i]);
$ipregex = preg_replace(“/\*/”, “.*”, $ipregex);
