PHP foreach loop & html table - displaying duplicates

Question

I am utilizing WordPress, ACF, and PHP; I've created a custom block with the code below. Please let me know if more information is needed. I am still fairly new to this and not sure what all to include.

The following code is working as intended with the exception of duplicating results. I did attempt to following through this thread with no luck. The picture included show what it's currently displaying. It should list APCS 207 Command Line Interface... APCS 242 Computer & Network Management... BUSI 270 Accounting Software Applications... BUSI 353 Advanced Accounting I...

<table style="width: 800px;">
<thead>
            <tr>
                <th>Course</th>
                <th>Course Name</th>
                <th>Course Credits</th>
            </tr>
</thead>

Answer 1

I was able to figure out. I added an if statement after the foreach($progcode_check_checked_values as $progcode_check_value). I was able to get the commented out $code = get_sub_field('discipline_code') to work as well. Updated code below.

<table style="width: 800px;">
<thead>
    <tr>
        <th>Course</th>
        <th>Course Name</th>
        <th>Course Credits</th>
    </tr>
</thead>

    <?php 
    $rawcourses = get_field('course_selector'); 
    $progcode_check_checked_values = get_field('prog_discipline_code'); 
    $i = 0;
    
    foreach($rawcourses as $rawcourse) : 
        if( have_rows('course_list', $rawcourse) ): ?>
    
        <?php
        while( have_rows('course_list', $rawcourse) ) : the_row(); 
            $code = get_sub_field('discipline_code');
        
            if ($progcode_check_checked_values) : ?>
            
            <?php foreach ($progcode_check_checked_values as $progcode_check_value) : ?>
                <?php if ($progcode_check_value == $code ) : ?>
