在Perl中,如何在数组中找到给定值的索引？

$VAR1 = [
          '830974','722065','722046','716963'
        ];

如何计算值“722065”的数组索引？

解决方法

List::MoreUtils的firstidx功能可以帮助您：

use strict;
use warnings;
use List::MoreUtils qw(firstidx);

my @nums = ( '830974','716963' );
printf "item with index %i in list is 722065\n",firstidx { $_ eq '722065' } @nums;

__END__

item with index 1 in list is 722065
