WAMPServer 登陆链接mysql就错误了，密码感觉没错啊，怎么连接不上，
就只有页面链接不上mysql，
phpmyAdmin可以连接的
<?php
$pdo = new PDO("mysql:host=localhost;dbname=testtwo","root","123456");
if($pdo -> exec("INSERT INTO author(id, name, email) VALUES(1, 'Kevin Yank', 'thatguy@kevinyank.com')")){
echo "插入成功！";
echo $pdo -> lastinsertid();
}
?>
