PHP实现的pdo连接数据库并插入数据功能简单示例

?php
$db_Type = "mysql";//数据库类型
$host = "localhost";//主机名
$dbName = "test";//数据库名
$userName = "root";//用户名
$password = "root";//密码
$dsn = "{$db_Type}:host={$host};dbname={$dbName}";
?>

?php
header('Content-type:text/html; charset=utf-8');
require 'pdo_config.php';
try{
    $pdo = new PDO ($dsn,$userName,$password);//创建一个连接对象
    $pdo->exec('set names utf8');//设置编码
    $sql = "INSERT student (name,email) VALUES ('李四','123@qq.com')";
    $pdo->exec($sql);
}catch (PDOException $e){
    die('操作失败'.$e->getMessage());
}
//关闭连接
$pdo = null;
?>
