PHP＋TEXT留言本(三)
上兩節我針對guest.php和edit.php作了講述.需要注意的是php和html的區別:php通常是-->(1)<? echo('zihanonline');?> (2)<? php echo('zihanonline'); ?> (3)<script laanguage='php'> echo('zihanonline'); </script> (4)<% echo('zihanonline');%>等4種方式.不要混淆.下面我們來研究信息管理:manage.php代碼.-----------//manage.php<html>
<head><title>留言管理</title><meta http-equiv='Content-Type' content='text/html; charset=gb2312'><style><!--A:link {text-decoration: none ; color:0000ff}A:visited {text-decoration: none; color:004080}A:active {text-decoration: none}A:hover {text-decoration: underline; color:ff0000}BODY {FONT-SIZE: 9p}TH {FONT-SIZE: 9pt}TD {FONT-SIZE: 9pt}--></style>
