What should I do with the database when I create a course in PHP with Moodle?
public function createCourse()
{
    //find category
    //calculate sortorder i.e. search in mdl course for all course with category. select sortorder MAX then ++
    require "/mysqli_connect.php";
    $t = time();
    $insert_q = "INSERT INTO mdl_course
    (category, fullname, shortname, summary, startdate, maxbytes,
    timecreated, newsitems, numsections, expirythreshold)
    VALUES (30, 'Fullname', 'shortname', 'This is the summary', '$t', 268435456, '$t', 5, 10, 864000)";

    $insert_r = mysqli_query($mysqli, $insert_q);
    $insert_n = mysqli_affected_rows($mysqli);
    //var_dump($insert_n);
    if($insert_n == 1)
    {
        return true; //insert successful
    }
    else
    {
        return false;
    }
}
