Instead of dressing this thread up with PDF stuff, why not break down the issue to what you assume the problem is - namely mysqli not returning data when you have a WHERE clause.

Not until way past line 100 do you start the important stuff:

$r2=$_GET['r']; 
$pdf=new PDF();
$header=array();
//Data loading
//*** Load MySQL Data ***//
include("connect.php");
$strSQL = "SELECT * FROM rfos"; //(this retrieve only first row)
//$strSQL = "SELECT * FROM rfos where r='$r2'";//(this does not retrieve anything)

This is very dangerous as you allow the user to inject SQL directly into your statement. You must use escaping functions or better still use prepared statements.

Error trapping / checking the query will help you with this too. We are assuming you actually have a field named 'r' and that there is always a querystring parameter named 'r'. If not you will get an error stating that the index does not exist. You should always have a conditional to apply a filter (WHERE) and bind any values if using prepared statement ...

if(isset($_GET['r'])){
//...
}else{
//...
}
