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").
