how 2 distinquish.	Can't Post

regular Expessions validation. Edit | Delete | Quote | Reply | Private Reply

I need to be a bit of a cheeky badger!

My program will take 2 types of user names. These will be in the format of 2 letters and 2 digits e.g zx12, OR 2 letters and 3 digits eg. as123. I need my program to distinguish between the 2.

if ($username =~ 2 letters and 2 digits) {

do this

}else if ($username =~ 2 letters and 3 digits) {

do this

}

Any help will be much appreciated cheers!!

Code

if ($username =~ /^[a-z]{2}\d{2,3}$/i) {

that doesn't do what the OP asked. it matches either name format but he wanted to distinguish between a 2 or 3 digit ending part. that should be an easy change for you to make so i won't do it myself.
