** 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.

Parameters

int	$userid	The user id
int	$limitfrom
int	$limitnum
int	$type	the type of the conversation, if you wish to filter to a certain type (see api constants).
bool	$favourites	whether to include NO favourites (false) or ONLY favourites (true), or null to ignore this setting.
bool	$mergeself	whether to include self-conversations (true) or ONLY private conversations (false) when private conversations are requested.

Return values

array the array of conversations

Then if we call: $conversations = get_individual_conversations_between_users([[1,2], [3,4], [5,6]]);

Where null is returned for the pairing of [3, 4] since no record exists.
