mrhenniger Posted March 16, 2010 Share Posted March 16, 2010 I am new to regular expressions but I hope to build some competance on the subject. For now though I am just a newbie. I am trying to create a regex were the haystack is expected to be small (only 10 characters or less), and a match is to be confirmed when the subject string fits the full length of the haystack. Here is the regex I have created in PHP... $number = preg_match("/^(N[CGLRSX]{0,1}[0-9]{1-3}[A-Z]{0,2})$/", $aCR); When I provide the values "N1Z" for $aCR, I expect to get a value of 1 for $number, but instead I get 0. Hmmmm.... What it looks straight forward, but obviously I am doing something wrong. Can anyone point out the error of my ways? Thanks in advance for any assistance you can provide.

cags Posted March 16, 2010 Share Posted March 16, 2010 Your concept is actually right, but I think you made a typo. {1-3} should obviously be {1,3}. I believe {1-3} would match itself as a literal string so your $aCR would have to be something like "N1{1-3}Z" in order to match the pattern.

mrhenniger Posted March 17, 2010 Author Share Posted March 17, 2010 That was it! If it wasn't for all of my typos I would be a genius. Thanks. Mike Quote Link to comment Share on other sites More sharing options...
