Hi,
Can someone tell me how to convert an array to hash.
Each array entry has a row of values
e.g. a(0) = ab cd ef; a(1) = mn de fg
The hash array needs to be constructed with one of the element in the
array row as the key.
e.g. hash{ab} = cd ef - ab is a string in the array row

I want to ready file in Hash Array.
I have file in following format:
ID | Time | IP | Code
open(INFO, $file);
@lines = ;
Instead of this I want to use Hash Array. May be just ID and IP fileds.

Example:
$ perl -MData::Dumper -wle '
my @array = qw/x t 3 u 77 y r/;
my %hash;
@hash{ @array } = ();
print Dumper(\%hash);
'
$VAR1 = {
'y' => undef,
my %hash;
@hash{ @array } = ();

Is there a way to find out if an entry exists in a hash array?
e.g. I have a hash array and another normal array. I would like loop
though regular array and see if the entries defined in this array exist
in hash array.

Hello,
I have to store more then one value in a hash array. I tried to store a
array as value in the hash. But when I try to retriev it I don't get the

Perl's hashes use a single key to look up a single value. So, to keep
this simple, you can use two hashes, %age

For arrays, yes. For hashes, no. scalar %hash produces something that looks
like this: 3/8, which is some measure of the number of buckets used by the
hashing algo (efficiency).
print scalar keys %hash, "\n";

ok...
scalar (@array);
scalar (%hash);
can be used to get the number of elements.
