Calling a stored procedure in PHP

$dbh = new mysqli($hostname, $username, $password, $database);
if (mysqli_connect_errno()) {
   printf("Connect failed: %s\n", mysqli_connect_error());
   exit();
}
if ($dbh->query("call error_test_proc(1)"))  /*execute stored procedure*/
{
   printf("Stored procedure execution succeeded");
}
else // Stored procedure failed - show error
{
   printf("<P>Stored procedure error: MySQL error %d (SQLSTATE %s)\n %s\n", $dbh->errno,$dbh->sqlstate,$dbh->error);      
}


Calling a stored procedure in PHP and deal with the result

<html>
<head>
<title>Employee listing</title>
</head>
<body>

<form method="post" >
<P>Enter Department ID:
<input type="text" name="dept_id" size="4">
<input type="submit" name="submit" value="submit"><P>
</form>
<?php
$hostname = "localhost";
$username = "root";
$password = "secret";
$database = "prod";
if (IsSet ($_POST["submit"])) {
     $dbh = new mysqli($hostname, $username, $password, $database);
     /* check connection */
     if (mysqli_connect_errno()) {
          printf("Connect failed: %s\n", mysqli_connect_error());
          exit ();
     }
     $dept_id = $_POST["dept_id"];
     if ($result_set = $dbh->query("call employee_list( $dept_id )")) {
          print ("<table border="1" width="30%"> <tr> ".
               "<td>Employee_id</td><td>Surname</td><td>Firstname</td></tr>");

               printf("<tr><td>%s</td><td>%s</td><td>%s</td></tr>\n", 
                      $row->employee_id, $row->surname, $row->firstname);
          }
     } else {
          printf("<P>Error:%d (%s) %s\n", mysqli_errno($dbh),
