Well, one problem is neither of your regex will match your string; the first will match strings which include 0-9 seven times in succession; the second will match seven consecutive copies of 0-9 or 0- or any combination of these; neither will match 7 random digits.

First suggestion: read the Perl documentation. Your regex are valid, but won't do what you want.

Second, and more helpful suggestion try:

/^\d{7}$/; which will match all strings which comprise exactly seven digits, with no non-numeric characters.

gOn's insertion of code tags made my entire reply nonsense

When in doubt, read the directions.
