一 代码
1、index.php
<?php
include_once("conn/conn.php"); //调用连接数据库的文件
include_once("function.php");
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>控制页面中输出字符串的长度</title>
<style type="text/css">
<!--
body {
margin-left: 0px;
margin-top: 0px;
margin-right: 0px;
margin-bottom: 0px;
}
a:link {
text-decoration: none;

}
-->
</style></head>
<body>
<table width="1147" height="813" border="0" align="center" cellpadding="0" cellspacing="0" >
<tr>
<td width="115" height="438"> </td>
<td width="378"> </td>
<td width="654"> </td>
</tr>
<tr>
<td height="121"> </td>
<td align="center" valign="top">
<table width="365" height="22" border="0" align="center" cellpadding="0" cellspacing="0">
<?php
$sql=mysql_query("select * from tb_new_dynamic order by id desc limit 0,6",$id);
while($myrow=mysql_fetch_array($sql)){
?>
<tr>
<td width="20" height="22"><div align="center"><img src="images/01.JPG"/></div></td>
<td width="258" height="22"><a href="new_dynamic.php?id=<?php echo $myrow["id"];?>" title="<?php echo $myrow["dynamic_title"];?>">

echo " ... ";
}
?>
</a> </td>
<td width="87"><?php echo "<font color=red>[".substr(str_replace("-","/",$myrow[createtime]),0,10)."]</font>";?></td>
</tr>
<tr>
<td colspan="3"></td>
</tr>
<?php }
?>
</table></td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
2、function.php
<?php
function msubstr($str,$start,$len) { //定义自定义函数的名称,控制文本输出字符的个数
$strlen=$start+$len; //获取文本的长度
for($i=0;$i<$strlen;$i++) { //循环输出文本中的字符
if(ord(substr($str,$i,1))>0xa0) { //截取文本中的字符
$tmpstr.=substr($str,$i,2); //截取文本中的字符
$i++;
}else
$tmpstr.=substr($str,$i,1);
}
return $tmpstr;
}
?>
3、new_dynamic.php
<?php
include_once("conn/conn.php"); //调用连接数据库的文件
include_once("function.php");
?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>最新动态详细内容</title>
<style type="text/css">
<!--
.STYLE1 {

}
body {
margin-left: 0px;
margin-top: 0px;

margin-bottom: 0px;
}
-->
</style>
</head>
<body>
<table width="1003" height="620" border="0" align="center" cellpadding="0" cellspacing="0" background="images/02.JPG">
<tr>
<td width="402" height="186"> </td>
<td width="458"> </td>
<td width="143"> </td>
</tr>
<tr>
<td height="341"> </td>
<?php
$sql=mysql_query("select * from tb_new_dynamic where id='".$_GET[id]."'",$id);
while($myrow=mysql_fetch_array($sql)){
?>
<td align="left" valign="top" class="STYLE1"><span class="STYLE1"><?php echo $myrow[dynamic_title];?>
<br>
<br>
<?php echo $myrow[dynamic_content];?></span></td>
<?php }?>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
4、conn.php
<?php
$id=mysql_connect('localhost','root','root'); //连接数据库服务器
mysql_select_db('db_database06',$id); //连接db_database06数据库
mysql_query("set names gb2312"); //指定数据库中字符的编码格式
?>
