$ivalue = 1;
$res = $mysqli->multi_query("CALL myproc($ivalue, @x);SELECT @x");
if ($res) {
  $results = 0;
  do {
    if ($result = $mysqli->store_result()) {
      echo "<b>Result #$results</b>:<br/>";
      while ($row = $result->fetch_row()) {
        foreach ($row as $cell) echo $cell, " ";
      }
      $result->close();
      if ($mysqli->more_results()) echo "<br/>";
