PCRE false match with preg_match?

I recently encountered a strange behaviour, could someone please countercheck it, to either tell me there is an error in my pattern? I have a test string: "7005-N/52" I have two match patterns: a) "/([0-9]*)\/(.*)/i" b) "/([0-9]*)\-(.*)/i" I check the test string with the help of preg_match, and they both matched, but normally variant a) shouldn't have matched. Normally I test my patterns with the tool "The Regex Coach", and according to this tool it shouldn't have matched. PHP version is 5.0.4, PCRE extension version is 4.5 01-December-2003 Thanks for any help or feedback, Jens
