1、如果是按ASCII码(字符串)排序,则代码如下:
1 foreach my $key ( sort { $hash{
$a} cmp $hash{ $b} } keys %hash ) {2 my $value = $hash{ $key};3 # do something with ($key, $value)4 }
2、如果是按数字大小排列,则代码如下:
1 foreach my $key ( sort { $hash{ $a} <=> $hash{ $b} } keys %hash ) {2 my $value = $hash{ $key};3 # do something with ($key, $value)4 }
