Perl 5 version 6.2 documentation


  • values HASH

    Returns a list consisting of all the values of the named hash. (In a scalar context, returns the number of values.) The values are returned in an apparently random order. The actual random order is subject to change in future versions of perl, but it is guaranteed to be the same order as either the keys or each function would produce on the same (unmodified) hash.

    Note that the values are not copied, which means modifying them will modify the contents of the hash:

    1. for (values %hash) { s/foo/bar/g } # modifies %hash values
    2. for (@hash{keys %hash}) { s/foo/bar/g } # same

    As a side effect, calling values() resets the HASH's internal iterator. See also keys, each, and sort.
