Why does split not return anything?

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.

Answer 2

the "." represents any character.You need to escape it for split function to recognise as a field separator. change your line to

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