If all of the functions are sure, you may call the functions by names in this way:

my %func_map={
  "function1" => \&function1,
  "function2" => \&function2,
  # .....
};

# while you got a name, call the corresponding function

my $name=some_way_you_got_it();
&{$func_map{$name}}($your_param1,$your_param2);
