以非常糟糕的PDF格式导出我的sql数据

Question

I have created a PDF from the data coming from a DB. But, after creation of PDF, it is not well formatted. How can I generate a well formatted PDF?
Another problem is that it is showing values one field before. For instance, in address field it shows results of phone number. Please visit this link and hit the PDF button at the given link and you will find a badly structured PDF file.How can I fix this?

mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
 ob_start();
