Perl $by lddzjwwy (Novice)
|on Jun 17, 2013 at 12:26 UTC||Need Help??|
lddzjwwy has asked for the
wisdom of the Perl Monks concerning the following question:
I got a question about the $ variables in Perl, if I have some codes like below:
Is the (\d+) inside the second if $1 or $2?.
It is only a simple example for figuring out what the second (\d+) should be. If there are some syntax errors pls ignore them.
Thanks a lot guys.
