(Usually.) * "\d+" is compound: - "\d" is the "digit" marker. (0-9) - "+" after it means "one or more". * "\." is just a period, but needs to be "escaped" in RegEx because it has special meaning. * "\s" is whitespace. * "/" surrounding the pattern are just delimiters. They are not part of the pattern itself. HTH, Todd Boyd Web Programmer -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
