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").
