[帮助]为什么没有显示? [英] [HELP] Why No Display?
问题描述
大家好,
我正在学习Gutmans,Bakken和他的PHP5 Power Programming回复并且来到了第58页。书中说输出是:
Judy
Joe
然而我从IE8和FF3都得不到任何结果相反!
我的机器是XP + PHP5 + Apache2.2。错误消息是:
可捕获的致命错误:类的对象无法在C中转换为字符串:\Program Files \ ... \ PHP5 PP\58 .php第24行
任何线索?
提前致谢,

Hi there,
I''m learning from PHP5 Power Programming by Gutmans, Bakken & Rethans and have come to p.58. The book says the output is:
Judy
Joe
However I get nothing from neither IE8 nor FF3 instead!
My machine is XP + PHP5 + Apache2.2. The error message is:
Catchable fatal error: Object of class Person could not be converted to string in C:\Program Files\...\PHP5 PP\58.php on line 24
Any clue?
Thanks in advance,

推荐答案

哦,不,Dormilich!即使我将相关代码更改为以下内容,仍然无法显示!怎么样?
