1. A preg_ expression has to have the delimeters '/^([^,]+),\s?(.*)/'.

Ah, well, that would make a difference. <http://akane.covisp.net/~kreme/vonage.phps> <http://akane.covisp.net/~kreme/vonage.php> $cid[$i]=preg_split('/^([^,]+),\s?(.*)/', $line, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY); Now it has an extra field in the array, but at least it is splitting the line.

    [6] => Array
        (
            [0] => (555) 555-5556
            [1] => Maggie, Fred, and George Cell
            [2] =>

2. Why do you need this complex expression to split at a comma? This '/,/' would do the trick. And even simpler explode(',', $line);

Because I need to split only at the FIRST comma.

Also your regex ^([^,]+) asks the perl regex parser to find the beginning of a line at which there is one or more instances of NO Comma. That is, [^ ] is a negation, so that [^0-9] means do not match any numbers.

Yes, and ^([^,]+) means, From the start of the line, get 1 or more characters that are not a comma and put them in \01.

So that any possible split would gobble up everything after the first instance in which the beginning of a line did not start with a comma, which would mean that you would get null results.

No, that's not right at all. As I said, the regex works (and has been tested in other ways).

3. Is there a reason why you are using the flag PREG_SPLIT_DELIM_CAPTURE?
