| Returns the contacts and their conversation to display in the contacts area. ** WARNING ** It is HIGHLY recommended to use a sensible limit when calling this function. Trying to retrieve too much information in a single call will cause performance problems. ** WARNING ** This function has specifically been altered to break each of the data sets it requires into separate database calls. This is to avoid the performance problems observed when attempting to join large data sets (e.g. the message tables and the user table). While it is possible to gather the data in a single query, and it may even be more efficient with a correctly tuned database, we have opted to trade off some of the benefits of a single query in order to ensure this function will work on most databases with default tunings and with large data sets. param: int $userid The user id param: int $limitfrom param: int $limitnum param: int $type the type of the conversation, if you wish to filter to a certain type (see api constants). param: bool $favourites whether to include NO favourites (false) or ONLY favourites (true), or null to ignore this setting. param: bool $mergeself whether to include self-conversations (true) or ONLY private conversations (false) return: array the array of conversations |
