PHP PDO变量插入与SQLite不兼容[重复]

when I run the following:

$pdo = new PDO('sqlite:/path/to/database.db');
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$stmt = $pdo->prepare('CREATE TABLE IF NOT EXISTS :user (id INTEGER PRIMARY KEY AUTOINCREMENT, time INTEGER NOT NULL, ping TEXT NOT NULL);');
$user = "me";
$stmt->execute(array('user' => $user));

I get the following error, referencing the :user part of the SQL:

PHP Fatal error: Uncaught PDOException: SQLSTATE[HY000]: General error: 1 near ":user": syntax error in /datasql.php:21 Stack trace: #0 /datasql.php(21): PDO->prepare('CREATE TABLE IF...') #1 {main} thrown in /datasql.php on line 21

I can't find anything wrong with the SQL and if I run the command without the variable insertion, it runs fine.

What is causing this error? Thanks ahead!
