Using the keys and values functions
Using the keys and values functions
- Perl also provides a convenient way to get a list of all the
keys or of all the values in an
associative array if you are
interested in more than just one key/value pair. Keys and
values are accessed with the keys and values functions
using the following formats:
@associative_array_keys =
keys (%ASSOCIATIVE_ARRAY_NAME);
- and
@associative_array_values =
values (%ASSOCIATIVE_ARRAY_NAME);
- Thus, the keys and values list of the associative array
%CLIENT_ARRAY defined above can be generated
with the following syntax:
@client_array_keys = keys (%CLIENT_ARRAY);
@client_array_values = values (%CLIENT_ARRAY);
- In this example @client_array_keys would look like
("full_name", "phone", "age") and @client_array_values
would look like ("Selena Sol", "213-456-7890", "27").
