Just loop through the filehandles you want to print to.

$file='/tmp/logfile';
open LOGFILE ,">>$file" or die "can't open $file: $!";
@t=qw/STDOUT LOGFILE/;
for (@t){
print $_ `echo $$`;
}

You can do this in a oneliner aswell, but this should be easier to understand.
I'm sure there is simpler ways and maybe even some module that has the equivalent functionality tee.
