使用php将Mysql数据导出为pdf

Question

I created a member registration webpage which allow user to feed his data (details like name, phone, address, particulars, etc.) there is a total of 25 such fields.
I use php and Mysql.
It is required that user should get acknowledgment along with details he entered. please let me know how to export that data to pdf file so that the user can print or save his data which he had entered.
