上两节我针对guest.php和edit.php作了讲述.需要注意的是php和html的区别: php通常是–>(1)<? echo(“zihanonline”);?> (2)<? php echo(“zihanonline”); ?> (3)<script laanguage=”php”> echo(“zihanonline”); </script> (4)<% echo(“zihanonline”);%> 等4种方式.不要混淆. 下面我们来研究信息管理:manage.php代码. ———– //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>
