preg_split

OK, I have this file: <web stuff> <?php

      $CID_FILE= 'vonage.callers';
      $lines=file($CID_FILE);
      foreach ($lines as $line) {
         $cid=preg_split('^([^,]+),\s?(.*)', $line, -1, PREG_SPLIT_DELIM_CAPTURE);

      }

?> <web stuff> the trouble is, $cid is empty. The actual file has lots of print lines, so I know that $lines is an array with each line for $CID_FILE as one element of the array and that $line gets the data from a single array element correctly. What I want is for each line to be an array, split at the first comma. The regex works in BBEdit, where I can search for ^([^,]+),\s?(.*) and replace with \2 \1 and it does the right thing, over and over, so the regex is not the issue. It's something that I am not doing right/understanding in preg_split. I've also tried: $cid=preg_split('^([^,]+),', $line); $cid=preg_split('^([^,]+),\s?(.*)', $line, PREG_SPLIT_DELIM_CAPTURE); $cid=preg_split('^[^,]+,', $line, -1); $cid=preg_split('^[^,]+,', $line); The actual code with the extra printing is here: <http://akane.covisp.net/~kreme/vonage.phps> <http://akane.covisp.net/~kreme/vonage.php> and the sample data is <http://akane.covisp.net/~kreme/vonage.callers> -- No one ever thinks of themselves as one of Them. We're always one of Us. It's Them that do the bad things.
