code:
UPDATE `table name` SET `column 1` = 'value 1',
`column 2` = 'value 2',
`value 3` = 'value 3' WHERE `id` = '1' LIMIT 1 ;
basically make a table with all the data you want to store, and have a column called id, put one record in it, with the ID as 1, and then just run that script every time you want to update it
