Re: Empty Delimiter error

Thanks so much Daniel. Indeed, the old line that I modified didnt use a function call. The old line was: if ($lines[$key] != $email){ So, the @ suggestion works just fine: if (!@stristr($lines[$key], $email)) { Seems like a cryptic syntax for an error code of this meaning - and odd that all the PHP sources I searched before posting here came up empty for the terminology.
