Printing items from an Hash using an Array

Gavin has asked for the wisdom of the Perl Monks concerning the following question:

Hi Brethren,
How can I alter this code so that it prints out both the key and the value from the hash for each item in the array

foreach (@array){    
    print(  $hash{$_}, "\n");
    
}

Thanks Gavin

A refinement of ikegami's for when you want to skip items in @array which are not keys of %hash, `for (grep {exists $hash{$_}} @array) { print $_, " :\t", $hash{$_}, "\n"; }` [download] After Compline, Zaxo	[reply] [d/l]

You can do something like this: `while (my ($k, $v) = each %hash) { print "$k: $v\n" }` [download] Where `$k` is the key and `$v` is the value. Igor 'izut' Sutton your code, your rules.	[reply] [d/l] [select]
