in thread How to store matched $1 values one by one to array?

Well, it's not an inconvenience, but that does now highlight where you're going wrong.

Declare your array outside of whatever loop iterates over your logfile and replace my @array=$agent_id; with a push statement, as I indicated.

    if($line =~ /^.*:agent_id=>(.+?),/){ # Calls count based on call type my $agent_value=$1; my $agent_value=~s/\"//g; push @agent_ids, $agent_value; print Dumper\@agent_ids; }

    Before while loop I have declared the @agent_ids and then added the push function with array and scalar variable.

    While printing the @agent_ids variable it printed the undef in array.

    I don't know why it is printing the undef values instead of exact values.

      $agent_value is declared two times.
      The substitution should not be used with my.
      Just remove the second lexical declaration and the code works.

      Also, I recommend to use strict and warnings.

      'warnings' says: "my" variable $agent_value masks earlier declaration in same scope at ...
      Remove the second my before $agent_value. It resets its value. Also, turn on warnings to be warned against the practice of redeclaring a variable.
