perl用变量做句柄介绍

#!/usr/bin/perl -w
use strict;
use warnings;
use FileHandle;
my %fh;
my @array = (1..10);
for(1..5){
        open $fh{$_},">$_.txt" or die;
}
for(1..5){
        #print $fh{$_} "$_\n";  此处错误
        $fh{$_}->print( "$_\n" );
　　  #为FileHandle里的函数 或 用（my $h = $fh{$_};  print $h "$_\n"；）亦可
 }
