Passing value through series of arrays

I've asked this question before but the answers were not significant to assisting me.

    $sql  = 'SELECT `name`, `course`, `id` FROM `teacher` ORDER BY `id` ASC';
    $rows = $mysql_conn->fetch_array($sql);
    // Teacher's Table (id / name / link /course)
    // Course default = 1-1-1-1-1-1-1-1

    foreach($rows as $record) { 
        $result[$record['name']] = $record['course']; 
        //$result["Moore,Tyler"] = "1-1-1-1-1-1-1-1";
        //$result["Craig,Joey"]  = "1-2-2-2-1-1-1-1";
        //$result["Degra,Tina"]  = "2-1-1-1-2-1-1-1";
    }

    foreach($result as $teacher=>$courses){
        $result[$teacher] = explode('-',$courses); // Remove -'s from courses and separate the array into sections
        //$result["Craig,Joey"][0] = 1;
        //$result["Craig,Joey"][1] = 2;
        //$result["Craig,Joey"][2] = 2;
        //$result["Craig,Joey"][3] = 2;
        //$result["Craig,Joey"][4] = 1;
        //$result["Craig,Joey"][5] = 1; 
        //$result开发者_如何转开发["Craig,Joey"][6] = 1;
        //$result["Craig,Joey"][7] = 1;
    }

    foreach($result as $teacher=>$courses){
        foreach($courses as $period => $course){
            if($course == $id) { // If course is equal to course page (selected course) record the period 1-8
                $name = explode(',', $teacher); // $name[0] = 'Craig' / $name[1] = 'Joey';
                $result[$period][] = '<a href="?page=teacher&id=">'.$name[0].'<br />'.$name[1].'</a>'; 
                // I want id= to get an id passed to it from the query
            }
        }
    }

I want to have the teacher's ID passed through so I can feature it into the link near the bottom of the code.

This is absolutely necessary however I can not seem to figure it all out without my head hurting.

Any help would be much appreciated! :)

I would add the teacher ID to their name:

$sql  = 'SELECT CONCAT(`name`, ",", `id`) AS `name`, `course` FROM `teacher` ORDER BY `id` ASC';

and then when you explode the teacher's name you will have their ID on index 2 (last name, first name, ID).
