Q:

Perl: How do I split AND cut a given String? 

I have a String that looks like this:
$string = "Tags: sweet, yummie, chocolate, dark"
I want to insert these Tags in a Mysql table. 

So how do I cut the [Tags:] out of the string? 
And how can I add foreach $string in a Mysql-table? 

A:

Start by removing the "Tags: " with a regex, and then split on ", ". 
my $string = "Tags: sweet, yummie, chocolate, dark"
$string =~ s/Tags: //;
my @tags = split /, /, @string;

For the MySQL connection, you could use DBI::MySQL.
