invaderzard, just wanted to make clear that this solution by Kenosis is the far quicker and easier version, which I'd, of course use anytime I'd just need a quick split by a field separator on an input.
But: There is one caveat here to keep in mind. Split, of course, does not test the format of the input. So if you wanted the second field of a record that goes like this:
does work. However so it does for inputs like:
All of the above inputs would leave a B in $second_field. Which, you know might be correct in a particular case, but in general, we don't want to just ignore malformed records, so if we, say, iterate over records, then make sure to test and capture using a regexp in an if:
Now this will only set $second_field if the record matches the four single-character fields delimited by one semicolon format. Even if the input is ';;;;;;;'. ;)
Have fun with regexen. They're cool. ;)
