I know that this is a kind of an old question, but today I was with the same issue. I didn't find a proper solution online and finally I solved, so I'm posting here so others can check.

I'm not 100% sure that this will work because I don't have your DB, but in my case was similar and worked. Also it will not be 100% like it was asked, but I'm pretty sure there will be no redundancy and all the data will be shown.

while ($row = mysqli_fetch_assoc($fetch)) {
$row_array ['school_name'][$row['school_name']]['terms'][$row['term_name']]['departments']['department_code'][$row['department_code']]['department_name'] = $row['department_name'];
$row_array ['school_name'][$row['school_name']]['terms'][$row['term_name']]['departments']['department_code'][$row['department_code']]['courses']['course_code'][$row['course_code']]['course_name'] = $row['course_name'];
$row_array ['school_name'][$row['school_name']]['terms'][$row['term_name']]['departments']['department_code'][$row['department_code']]['courses']['course_code'][$row['course_code']]['sections']['unique_id'][$row['magento_course_id']]['section_code'] = $row['section_code'];
}

Also I'm not a PHP guy, but from what I understand, the = comes before a leaf and only before a leaf.
