代码如下,运行并没有出错,但是就是没有创建表
try{ $pdo = new PDO('mysql:host:localhost;dbname=test','root','136189'); } catch(PDOException $e) { echo $e->getMessage(); } $sql=<<<STR CREATE TABLE IF NOT EXISTS users( id INT UNSIGNED PRIMARY KEY AUTO_INCREMENT, username VARCHAR(20) UNIQUE NOT NULL, password CHAR(32) NOT NULL, email VARCHAR(30) NOT NULL ); STR; $a = $pdo->exec($sql);
