So I have a database table that is structured something like this...
NAME | PHONE | EMAIL1 | EMAIL2 | EMAIL3
Those would be my columns, imagine this is a row in that database..
John | 555-555-5555 | email1@website.com | email2@website.com | email3@website.com
I need to be able to dump these entries to a CSV which I have the code for working already BUT the format is the issue.
I need each email to be displayed on a single row with the corresponding name and number, in the following format...
John | 555-555-5555 | email1@website.com
John | 555-555-5555 | email2@website.com
John | 555-555-5555 | email3@website.com
I need to retrieve thousands of rows and display them this way, is there some way using a PHP while loop I can display the rows from my database table in this format? Any help is greatly appreciated.
This process is called unpivoting.
And is most commonly done with UNION ALL
within MySQL.
SELECT
NAME
, PHONE
, EMAIL1
FROM
table
UNION ALL
SELECT
NAME
, PHONE
, EMAIL2
FROM
table
UNION ALL
SELECT
NAME
, PHONE
, EMAIL3
FROM
table
