multithreading - Not able to push into array from subroutine in perl -


i using multithread , want push local time of each thread array. can print localtime thread successfully, wont push time array. printing array not giving blank.

please check.

my code:

#!/usr/bin/perl use threads; use www::mechanize; use lwp::useragent;  @arr=(); $num_of_threads = 2; @threads = initthreads();  foreach(@threads){          $_ = threads->create(\&dooperation);          }  foreach(@threads){          $_->join();          }  foreach(@arr){          print "$_\n";          }  sub initthreads{             @initthreads;             for(my $i = 1;$i<=$num_of_threads;$i++){                 push(@initthreads,$i);              }             return @initthreads;         }  sub dooperation{         ##doing main operation here         $a=localtime();         print "$a\n";         push(@arr,$a);         }

threads don't share variables. see threads::shared.

use threads; use threads::shared; @arr :shared;
