query('SET NAMES utf8');
function cd(){global $pdo;return $pdo->lastInsertId();}
function qr($var){global $pdo;return $pdo->query($var);}
function fo($var){return qr($var)->fetch();}
function fa($var){return qr($var)->fetchALL();}
$fp=fo('SELECT * FROM post WHERE id=1');
echo $fp['title'];
echo $fp['content'];

这样写的话页面什么也不现实

{
//问题出在这里,qr($var)的值是$pdo->query($var)的值,是一个sql的执行结果,而不是对象$pdo,调用fetch肯定出错啊
return qr($var)->fetch();
