1. A preg_ expression has to have the delimeters '/^([^,]+),\s?(.*)/'.
Ah, well, that would make a difference.

$cid[$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?
I tried many different variations.
