Displaying a list with numerous values - php

Question

I was hoping somebody may be able to help with my problem.
I am using the following query
$query = $db->prepare("SELECT p.pattern_for,
c_main.name AS cat_name, c_main.slug AS cat_slug,
c_sub.name AS sub_cat_name, c_sub.slug AS sub_cat_slug
FROM products AS p
INNER JOIN categories AS c_main ON c_main.name = p.c_main
INNER JOIN categories AS c_sub ON c_sub.name = p.c_sub
WHERE p.stock_level > 0 AND p.pattern_for != ''
GROUP BY p.pattern_for
ORDER BY p.pattern_for ASC");
$query->execute();
The above works fine however I want to give the person creating the products the ability to be able to add numerous values to the column 'pattern_for'.
So it could have the following values -
Product A - 'Men, Women, Children
Product B - 'Women'
Product C - 'Toddlers, Girls'
Product D - 'Men, Boys'
Product E - 'Girls, Women, Babies'
What I need it to do is (in the query) split the values using the comma and then display them all in a list but also grouping them so it only shows once and also ordering alphabetically.
So for example the output of the above would be...
Babies
Boys
Children
Girls
Men
Toddlers
Women
Is this possible?

For those who may come across this problem in the future here is the query I ended up using...
$query_pattern_for = $db->prepare("SELECT p.pattern_for,
c_main.name AS cat_name, c_main.slug AS cat_slug,
c_sub.name AS sub_cat_name, c_sub.slug AS sub_cat_slug
FROM products AS p
INNER JOIN categories AS c_main ON c_main.name = p.c_main
INNER JOIN categories AS c_sub ON c_sub.name = p.c_sub
WHERE c_main.type = 0 AND c_sub.type = 0 AND p.stock_level = 0 AND p.reorder = 0 AND p.pattern_for != '' AND p.status = 1
OR c_main.type = 0 AND c_sub.type = 0 AND p.stock_level > 0 AND p.pattern_for != '' AND p.status = 1
GROUP BY pattern_for
ORDER BY p.pattern_for ASC");
$query_pattern_for->execute();
$count_pattern_for = $query_pattern_for->rowCount();
and then the php...
while ($row = $query_pattern_for->fetch(PDO::FETCH_ASSOC)) {
$get_pattern_for .= $row['pattern_for'] . ',';
}
$get_pattern_for = str_replace(', ', ',', $get_pattern_for);
$get_pattern_for = explode(",", $get_pattern_for);
$get_pattern_for = array_unique($get_pattern_for);
$get_pattern_for = array_filter($get_pattern_for);
sort($get_pattern_for);
foreach($get_pattern_for as $pattern_for) {
$pattern_for_slug = str_replace(' ','',$pattern_for);
$pattern_for_slug = str_replace('/','-',$pattern_for_slug);
$pattern_for_slug = preg_replace('/[^\w-]/', '', $pattern_for_slug);
$pattern_for_slug = strtolower($pattern_for_slug);
echo '<li>'; if ($get_patterns_for == $pattern_for_slug) { echo '<div class="tick-box-selected">✔</div>'.$pattern_for.''; } else { echo '<div class="tick-box"></div>'.$pattern_for.''; } echo '</li>';
}
I hope this helps somebody out someday.
Thank you
