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;
?>
