Perl：grep数组中数组的值(Perl: grep a value in array in array)

Perl：grep数组中数组的值(Perl: grep a value in array in array)

如何从数组数组grep值？ 我的尝试：

my $match =grep (/value/, @array); if ( $match <= 0 ) { ... }

我总是将零作为输出不正确。

我能够在2之后打印$ value，循环所以我认为grep只有在有1个循环时才能工作。

for $value (array) { for my $value1 (@$value) { print $value1 };

谢谢。

How do I grep values from an array of arrays? My attempt:

my $match =grep (/value/, @array); if ( $match <= 0 ) { ... }

I am always getting zero as a output which is incorrect.

I am able to print $value after 2 for, loops so I think grep will only work when there is 1 loop.

for $value (array) { for my $value1 (@$value) { print $value1 };

Thanks.

将第一级数组grep转换为@result

my @result = grep { grep { /search/ } @$_ } @array;

将最终字符串写入@result ，

my @result = grep { /search/ } map { @$_ } @array;

To grep first level of arrays into @result

my @result = grep { grep { /search/ } @$_ } @array;

grepping final strings into @result,

my @result = grep { /search/ } map { @$_ } @array;
