對象執行個體化後訪問不了

class person{
var $name;
function say(){
echo "hello！";
}
}
$P = new person;
$p->name="TOM";
$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
哪裡出錯了，新手求教，我照著書上碼的。

回複討論(解決方案)

$P = new person;
$p->say();

php 的變數是區分大小寫
$P 和 $p 是兩個變數
