Question

I am trying to get that Perl split working for more than 2 hours. I don’t see an error. Maybe some other eyes can look at it and see the issue. I am sure its a silly one:

@versionsplit=split('.',"15.0.3");

print $versionsplit[0];
print $versionsplit[1];
print $versionsplit[2];

I just get an empty array. Any idea why?

Answer 1

You need:

@versionsplit=split(/\./,"15.0.3");

The first argument to split is a regular expression, not a string. And . is the regex symbol which means ‘match any character’. So all the characters in your input string were being treated as separators, and split wasn’t finding anything between them to return.
