printf("Connect failed: %s\n", mysqli_connect_error());

/* execute query */
   
$stmt->execute();

/* close statement */
   
$stmt->close();
}

/* close connection */
$mysqli->close();
?>

例 1341. Procedural style

/* check connection */
if (mysqli_connect_errno()) {

   exit();
}

mysqli_query($link, "CREATE TABLE myCountry LIKE Country");
mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");

if (

/* drop table */
   
mysqli_query($link, "DROP TABLE myCountry");

mysqli_stmt_execute($stmt);

   
printf("Error: %d.\n", mysqli_stmt_errno($stmt));

   
/* close statement */
