Separating a single linebreak-separated value into multiple values in MySQL - php

Question

I have a table that puts multiple values into a single value in MySQL, separated by linebreaks. Like this:
+------------+-------------+
| Company | Products |
| (VARCHAR) | (TEXT) |
+------------+-------------+
| Acme Corp | Medicine |
| | Food |
| | Phones |
+------------+-------------+
| Ajax Corp | TVs |
| | Phones |
| | Pianos |
+------------+-------------+
I can't do anything about the table structure. Now I need a query that will return this table:
+==========+
| Products |
+==========+
| Food |
+----------+
| Medicine |
+----------+
| Phones |
+----------+
| Pianos |
+----------+
| TVs |
+----------+
I prefer a pure MySQL approach, but a solution with PHP is also OK for me.

Answer 1

There are no handy ways to split a field with MySQL. (Check the comments in the MySQL documentation). So, the best method seems to obtain all the product records with a simple:
SELECT Products FROM YourTable
And after in you php code:
$products = array_merge($products, explode("\n", $record));
for each record.

Answer 2

This will work for 3 products maximum,for more it needs a bit of tinkering
CREATE TABLE t
(
company varchar(20),
products text
);
INSERT INTO t
VALUES
('Acme', 'Medicine,Food,Phones'),
('ajax', 'TVs,Phones,Pianos');
SELECT SUBSTRING_INDEX(Products,',',1) FROM t
UNION
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(CONCAT(Products,','),',',2),',',-1) FROM t
UNION
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(CONCAT(Products,','),',',3),',',-1) FROM t
WHERE SUBSTRING_INDEX(Products,',',1)<>''
AND SUBSTRING_INDEX(SUBSTRING_INDEX(CONCAT(Products,','),',',2),',',-1) <>''
AND SUBSTRING_INDEX(SUBSTRING_INDEX(CONCAT(Products,','),',',3),',',-1)<>''
Results
Medicine
TVs
Food
Phones
Pianos
