Perl: Creating new variables inside a loop -

i have code following:

 $player_2ubid = grep { $_->ubid eq "2ubid" } @{$room_members };  $player_3ubid = grep { $_->ubid eq "3ubid" } @{$room_members };  # ....  $player_11ubid = grep { $_->ubid eq "11ubid" } @{$room_members }; 

to avoid repetition, want go loop

for $i ( 2 .. 11 ){ $player_.$i.ubid = grep { $_->ubid eq "$i.ubid" } @{$room_members }; } 

however produces syntax error:

can't modify concatenation (.) or string in scalar assignment @ ***.t line 100, near "};" 

what doing wrong here?

first have write $i."ubid" or "${i}ubid" instead of "$i.ubid".

and i'd use hash like:

my %player_ubid; $i ( 2 .. 4 ){     $player_ubid{$i} = grep { $_->ubid eq $i."ubid" } @{$room_members }; }
