Save changes to a user account or add a new user.

Parameters

$account: The user object for to modify or add. If you want to modify an existing user account, you will need to ensure that (a) $account is an object, and (b) you have set $account->uid to the numeric user ID of the user account you wish to modify. Pass in NULL or any non-object to add a new user.

$array: (optional) An array of fields and values to save. For example, array('name' => 'My name'); Keys that do not belong to columns in the user-related tables are added to the a serialized array in the 'data' column and will be loaded in the $user->data array by user_load(). Setting a field to NULL deletes it from the data column, if you are modifying an existing user account.

$category: (optional) The category for storing profile information in.

Return value

A fully-loaded $user object upon successful save or FALSE if the save failed.
