       2    20   2
       3    40   1

note: the result should be displayed as a string thanks

the function which i used to create the string is

$a=var_export($_REQUEST);
$b ='';
foreach($_REQUEST as $key=>$value)

    $b.=$key."+".$value."+";
}

</div>

$array = array();
foreach ($_REQUEST as $key => $value) {
  preg_match('/^([a-z]+)(\d+)$/', $key, $match);
  $array[$match[2]][$match[$1] = $value;
}
echo "<table><tr><th>pid</th><th>price</th><th>qty</th></tr>";
foreach ($array as $row) {
  echo "<tr><td>$row[pid]</td><td>$row[price]</td><td>$row[qty]</td></tr>";
}
echo "</table>";
