mysqli_multi_query（） - 返回true而不是返回数据

Question

So, I have written some query code returns the error:

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given

I understand that this is caused to a boolean response from the query, and I have checked it out, and the Boolean returned is equal to true. So I don't see why there is no response with a data array instead... Here's my code:

$data = mysqli_multi_query($connection, 'UPDATE teams SET teams.teamViews = teams.TeamViews
 + 1 WHERE (teams.teamID, \''.$userToken.'\') NOT IN (SELECT teams_views.teamId,
teams_views.'.$viewType.' FROM teams_views) AND teams.teamUrl = \''.TEAM_URL.'\';
INSERT INTO teams_views (teamId, '.$viewType.') SELECT t.teamId, \''.$userToken.'\'
FROM teams t WHERE t.teamUrl = \''.TEAM_URL.'\' AND NOT EXISTS (SELECT \''.$userToken.'\'
FROM teams_views WHERE t.teamId = teamId);
SELECT * FROM teams WHERE teams.teamUrl = \''.TEAM_URL.'\';');
$dataRow = mysqli_fetch_array($data, MYSQLI_ASSOC);

There are three queries in the SQL - An update, insert, and selection.

How could I alter my query or PHP to return data, rather than a boolean? Thanks

As suggested in a comment by spencer7593 , my question was solved using a combination of mysqli_store_result , mysqli_free_result , and mysqli_next_result . The following is the function used to do this:

function multi_queries($query, $numQueries) {
    $connection = new database_connection();
    $data = mysqli_multi_query($connection->connection, $query) or die(mysqli_error($connection->connection));
    $data = mysqli_store_result($connection->connection);
    if (sizeof($data) > 0) {
        $this->success = true;
        do {
            if ($result = mysqli_store_result($connection->connection)) {
                while ($row = mysqli_fetch_row($result)) {
                    $this->data[sizeof($this->data)] = $row;
                }
                mysqli_free_result($result);
            }
        } while (mysqli_next_result($connection->connection));
    }
    $connection->close_connection();
}
