		  foreach ($rec as $arr => $num){
			  $details .='<tr>';
				 foreach ($num as $title => $value){
					 if(!is_array($value)){
						$details .='<td>'.$value.'</td>';
					 }
				 }
			  $details .='</tr>';	 
		  }
		  
	$data .=$details.'</table>'; 
	
	echo '<pre>'.$data.'

$details ='';

$data = '<table width="500" cellpadding="1" cellspacing="1" border="0" class="dnsDetailsTable">';

foreach ($rec as $arr => $num){

$details .='<tr>';

foreach ($num as $title => $value){

if(!is_array($value)){

$details .='<td>'.$value.'</td>';

}

$details .='</tr>';

}

$data .=$details.'</table>';

echo '<pre>'.$data.'

’;
