上一次我们研究了guest.php文件.具体的问题还要求读者朋友自己深入的去实践,而且需要一些工具书来学习,如果您一点php的知识都没有,笔者奉劝您就不要想下看了,笔者没有太多的时间和篇幅去逐句探究一个php文件的用途和意义.好的,接下来我们来作edit.php这个文件. ----------- //edit.php <? if ($Submit) { if ($SavePassword=="on") {setcookie("TxtPassword","$TxtPassword",time()+30*24*3600);} else {setcookie("TxtPassword");} } ?> <html> <style type=text/css> Td {FONT-SIZE: 10pt;} TEXTAREA { FONT-FAMILY: "宋体"; FONT-SIZE: 10pt; } </style> <head> <meta http-equiv="Content-Language" content="zh-cn"> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title>修改留言</title> <?
