Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality - development

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality I would really like to know if there is a way like MS Word mailmerge functionality that can be done using PHP and Mysql data. Like i have address data in MySQL (suppose 10 numbers) and through PHP i want to insert that address data in a pre-defined letter head area. And it will automatically generate 10 different letters with same content but different address in PDF. Can it be done? Any start up point will be helpful.
