29 * Implement the "match" and "match-mandatory" options. If the submitted record doesn't have an ID
30 * but a "match" key is specified, then we will automatically search for pre-existing record and
31 * fill-in the missing ID. The "match" or "match-mandatory" can specified as a string (the name of the key
32 * to match on) or array (the names of several keys to match on).
34 * Note that "match" and "match-mandatory" behave the same in the case where one matching record
35 * exists (ie they update the record). They also behave the same if there are multiple matching
36 * records (ie they throw an error). However, if there is no matching record, they differ:
37 * - "match-mandatory" will generate an error
38 * - "match" will allow action to proceed -- thus inserting a new record
41 * $result = civicrm_api('contact', 'create', array(
43 * 'match' => array('last_name', 'first_name')
45 * 'first_name' => 'Jeffrey',
46 * 'last_name' => 'Lebowski',
47 * 'nick_name' => 'The Dude',
