通过PHP PDO创建MySQL表后无法插入

我对PDO和MySQL相当陌生，并且遇到了一个奇怪的问题。我查看了很多PDO和MySQL线程，但没有人似乎有这个确切的问题。通过PHP PDO创建MySQL表后无法插入

当我创建数据库，新的mysql新用户，一个表和几列后，我无法使用INSERT INTO来填充数据库。 PDO引发以下错误：

SQLSTATE [42S02]：基表或视图未找到：1146表“cms01db.cms_settings”不存在

如果我看在phpMyAdmin，数据库中存在，该表和列存在，排序正确等。如果我然后在PHPMyAdmin中删除表并在那里手动重新创建它，具有完全相同的规格，我可以使用相同的INSERT INTO脚本，它工作得很好。

我在做什么错？

脚本来创建数据库：

// define server and root login 
$servername = 'localhost'; 
$username = 'root'; 
// define new user for new database and login password 
$newUser = 'admin'; 
$newPass = 'password'; 
$dbname = 'cms01db'; 

// create database 
try { 
// connect to mysql and login 
$conn = new PDO("mysql:host=$servername", $username); 
// set the PDO error mode to exception 
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
// setup command to create database, new user and asign to new database 
$sql = "CREATE DATABASE `$dbname` CHARACTER SET ascii COLLATE ascii_general_ci; 
     CREATE USER '$newUser'@'localhost' IDENTIFIED BY '$newPass'; 
     GRANT ALL ON `$dbname`.* TO '$newUser'@'localhost'; 
     FLUSH PRIVILEGES;"; 
// use exec() because no results are returned 
$conn->exec($sql); 
echo "Database created successfully<br>"; 
} 
// if shit goes wrong... 
catch(PDOException $e) 
{ 
// display error why 
echo $sql . "<br>" . $e->getMessage(); 
} 
// terminate db connection 
$conn = null;

脚本来创建表和列：

// login with new user and create database tables & columns 
try { 
    // connect to mysql and login 
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $newUser, $newPass); 
    // set the PDO error mode to exception 
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
    // sql to create table and columns 
    $sql = "DROP TABLE IF EXISTS cms_setings; 
      CREATE TABLE cms_setings (
      measurements VARCHAR(1) NOT NULL, 
      brasizes VARCHAR(3) NOT NULL, 
      shoesizes VARCHAR(3) NOT NULL 
      )"; 
    // use exec() because no results are returned 
    $conn->exec($sql); 
    echo "CMS Settings Table created successfully<br>"; 
} 
// if shit goes wrong... 
catch(PDOException $e) 
{ 
    // display error why 
    echo $sql . "<br>" . $e->getMessage(); 
} 
// terminate db connection 
$conn = null;

脚本插入到：

//prepare variables 
//measurements: 'm' for metric, 'i' for inches 
$measurements_data = 'i'; 
//brasizes: 'us' for USA/Canada, 'uk' for UK, 'aus' for Australia, 'eu' for Europe, 'bef' for Belgium/Spain/France 
$brasizes_data = 'us'; 
//shoesizes: 'us' for USA/Canada, 'uk' for UK, 'eu' for Europe, 'jap' for Japan 
$shoesizes_data = 'us'; 

// login and insert data into columns 
try { 
    // connect to mysql and login 
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $newUser, $newPass); 
    // set the PDO error mode to exception 
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
    // sql to create insert data 
    $sql = "INSERT INTO cms_settings (measurements,brasizes,shoesizes) VALUES (:measurements,:brasizes,:shoesizes)"; 
    //prepare the statement 
    $stmt = $conn->prepare($sql); 
    // execute statement 
    $stmt->execute(array(':measurements' => $measurements_data, 
        ':brasizes' => $brasizes_data, 
        ':shoesizes' => $shoesizes_data)); 
    echo "CMS Setting Populated Successfully<br>"; 
} 
// if shit goes wrong... 
catch(PDOException $e) 
{ 
    // display error why 
    echo $sql . "<br>Error: " . $e->getMessage(); 
} 
// terminate db connection 
$conn = null;

似乎是一个错字：'cms_setings'，而不是'cms_settings'。 – Federkun

@Leggendario - 你打我吧：D – Jesse

亲爱的主，现在我觉得很蠢哈哈。非常感谢！现在完美的工作^ _ ^令人难以置信的是，你可以在几小时和几小时盯着相同的代码时发现这样的微小错误... – Insomniaboy

在你的代码有拼错。行

 CREATE TABLE cms_setings (

更改为

 CREATE TABLE cms_settings (

干杯
