note davido <p>Keys in hashes are unique. The only way for a key to have multiple values is if the "value" is a reference to some container (an anonymous hash, anonymous array, or some object). Let's say your hash holds references to arrays. You might do this:</p> <c> my %hash = ( unwanted => [1], wanted => [2, 3, 4] ); my $target_key = 'wanted'; if( exists $hash{ $target_key } && ref $hash{ $target_key } eq 'ARRAY' && @{ $hash{ $target_key } } > 1 ) { print "The element associated with $target_key holds a reference to an array of @{$hash{$target_key}} values.\n"; } </c> <div class="pmsig"><div class="pmsig-281137"> <br /><p>Dave</p> </div></div> 1003939 1003939
