in my php,
while($info3 = mysql_fetch_array($result3)){
$Name = $info3[\"Name\"];
$Address = $info3[\"Address\"];
$Age = $info3[\"Age\"];
// ----------------
If what you mean is you want one table that includes all the results as rows, only loop the row printing and migrate the opening and closing tags outside the loop.
$tbl = '';
while($info3 = mysql_fetch_array($result3)){
$Name = $info3["Name"];
$Address = $info3["Address"];
$Age = $info3["Age"];
$tbl .= '
'.$Name.'
'.$Age.'
'.$Address.'
'
}
$tbl .= '
';
$pdf->writeHTML($tbl, true, false, false, false, '');
