Question

我在perl中创建一个简单的IRC bot，我认为能够添加管理员会很有用。所以我在顶部，声明了这个数组，有几个用户。这很好用，机器人识别我，并在我进入时选择我。我已经声明了这个数组：

    my @adms=('user@host');

然而，我让机器人在while（1）循环中运行，因此它处于活动状态，并且处于睡眠状态。当我试图运行-adduser（这是内环这个循环）时，更改不会持续存在，我已经读过这是除了for（）循环之外的任何东西中的正常行为，但这对于无用是有害的。

if ( $funcarg =~ /^-adduser (.*)/ ) {
    my $user = "$1";
    sendraw( $IRC_cur_socket, "PRIVMSG $printl $pn" );
    push( @adms, $user );
    my $p = join( ", ", @adms );
    sendraw( $IRC_cur_socket, "PRIVMSG $printl Current admins are now $p" );
}

如何让这些更改持续存在，我能够做些什么来改变这种变化？

编辑：我没有说清楚这一点。所以我将添加更多的代码和解释，以期澄清。抱歉任何歧义。

您正在分叉和修改子进程中的值，并且子进程所做的更改不能更改父进程中的值。

考虑您确定问题的功能：

# This is where I have bot functions going on, and it's when I do this code,
# it doesn't update the main @adms array; the change seems to dissapear instantly. 

sub bfunc {
   my $printl = $_[0];
   my $funcarg = $_[1];
   if (my $pid = fork) {
      waitpid($pid, 0);
   } else {
      if (fork) {
         exit;
      } else {
         if ($funcarg =~ /^-adduser (.*)/) {
         my $user="$1";
          push(@adms, $user);
         my $p=  join(", ", @adms);
          sendraw($IRC_cur_socket, "PRIVMSG $printl Current admins are now $p");
         }
        }
    }
}

父进程分叉并等待;孩子也分叉，然后退出。然后，孙子进程会修改自己的@adms数组，但它所做的更改不会反映在父进程中。

Perl更改为数组不持久
