filter data from 2 array

[edwardsal]

how I can filter only data that = I want from 2 array?

I have to array

@array1=("1","2","3");
@array2=("1");

so how I can make if statment if some element from array1=array2 than true else false?

Might have to put a few more words around that. Do you mean that for each element n you want to compare $array1(n) with $array2(n) ?

Or do you want to check to see if $array1(n) can be found anywhere in @array2 ?

Post what you have so far, as well, as this might give a clearer indication of what you want...

my @a1=("1","2","3");
my @a2=("1");

my @conditionals = map {defined $a1[$_] && defined $a2[$_] && $a1[$_] eq $a2[$_]} (0..($#a1> $#a2? $#a1: $#a2))

# @conditionals equals (1, '', '')

I doubt this is really want you want. You were extremely unclear and honestly sounded drunk in your description. But if you really are drunk, then you won't notice when this code isn't what you want, and will give me a star anyway.

Cheers!
