what that's supposed to do is this:
if it's blank or not 10 or 11 digits...
The question is where is my understanding faulty or did I mess up.
I hope I understood you right now; I think you want the !~ operator.
my $user1 = 'foobar';
my $user2 = '10100101011';
if(!defined($user1) || $user1 !~ /[0-9]{10,11}/) {
print "User 1 $user1 is not legal\n";
}
else {
print "$user2 is legal";
}
if(!defined($user2) || $user2 !~ /[0-9]{10,11}/) {
print "User 2 $user2 is not legal\n";
}
else {
print "$user2 is legal\n";
}
