Well, I never got errors,
but there was a missing ";" at teh end of the preg_match.
But... it didn't work anyway.
Here's the fixed version, that I even bothered to test for you.
<?
$str = "[Tue Apr 09 03:54:00 2002] [1 jimistight2@yahoo.com] Jim (Customer) <Group A>";
preg_match('/([.])\s([.])\s([a-z])\s((.))\s(<.*>)/is',$str,$array);
print_r($array);
?>
