Re: Regex help

>I will have a variable: $the_extention which will have a value like: >98797-234234--2c-something-2c > >How do I take out the part which will always start with "--2c" and will >always end with "-2c" You could use preg_replaces, like so: $result = preg_replace('/--2c.+-c/', '', $the_extention); That matches anything between '--2c' and '-2c' and replaces it with ''. You could also use preg_match, like so: preg_match('/^(.+)--2c.+-c$/', $the_extention, $matches); $matches[1] should contain the substring you need. >A good "baby steps" tutorial on regex too would be appreciated. Chapter 7 of Learning Perl is an excellent tutorial and basic reference. http://www.oreilly.com/catalog/lperl3/ As usual, the trusty PHP manual also has good information: http://www.php.net/manual/en/pcre.pattern.syntax.php --------------------------------------------------------------------- michal migurski- contact info and pgp key: sf/ca http://mike.teczno.com/contact.html
