$p->say();
?>
notice: undefined variable: p in i:\www\phpnow-1.5.6.4237493736\package\htdocs\democlass.php on line 10
fatal error: call to a member function say() on a non-object in i:\www\phpnow-1.5.6.4237493736\package\htdocs\democlass.php on line 10
哪里出错了，新手求教，我照着书上码的。
回复讨论(解决方案) $p = new person;
$p->say();
php 的变量是区分大小写的
$p 和 $p 是两个变量
