1 以文件名来保存发言和回复
// max.txt保存着最大的发言标题总数(不包括回复)
论坛分级文件...
第一个发言的文件名叫 1.txt
第一个发言的回复1 叫 1_1.txt
第一个发言的回复2 叫 1_2.txt
第一个发言的回复2的回复1叫 1_2_1.txt
第二个发言的文件名叫 2.txt
2 显示方法
<?
//得到标题文章总数(不包括回复的文章)
$max = file("max.txt");
//分页显示
if($page == "")
{
$page = 1;
}
//每页显示的标题数目
$numperpage = 20;
//总标题数
$total = $max[0];
//总页数
$totalpage = round( ($total+$numperpage/2)/$numperpage );
//分级显示的函数
function show($filename)
{
//$id为论坛的分类名称
global $id;
//读入要显示的发言
$filenamemsg = file($filename);
//分割
$msg = split("\|\|bbs\|\|",$filenamemsg[0],99);
//显示当前的发言标题
print("<li type=square><a href=# onClick=\"window.open('detail.php?f
ilename=$filename&&id=$id','detail','menubar=0,toolbar=0,location=no,s
tatus=no,directories=0,scrollbars=yes,resizable=no,left=10,top=10,widt
h=550,height=400')\">".$msg[2]." ".$msg[0]." ".
$msg[4]."\r\n");
/查找是否有回复
for($i=1;$i<999999;$i++)
{
//查找是否有 文件名_数字 的回复文件
$tmp = $filename."_".$i;
if( file_exists($tmp) )
{
//如果有,则调用递归显示这个回复以及回复的回复
print("\r\n");
show($tmp);
print(" \r\n");
}
else
{
//否则中断循环
break;
}
}
//分级显示结束
print("");
}
//分页显示开始
$begin = $total-($page-1)*$numperpage;
//分页显示结束
$end = $begin - $numperpage;
//分级显示开始
print("");
//循环显示标题以及各级回复
for($i=$begin;($i>0) && ($i>$end);$i--)
{
show("$i");
}
//分级显示结束
print(" ");
3 发表新文章的方法
//处理最大发言数
$max = file("max.txt");
$maxnumber = $max[0]+1;
$handle = fopen("max.txt","w");
fputs($handle,$maxnumber);
fclose($handle);
//新建发言标题文件
$handle = fopen("$maxnumber","w");
//对发言进行预处理
$name = ereg_replace("<","<",$name);
$name = ereg_replace(">",">",$name);
if( strlen($name) > 20 )
{
$name = substr($name,0,20);
}
$email = ereg_replace("<","<",$email);
$email = ereg_replace(">",">",$email);
if( strlen($email) > 50 )
{
$email = substr($email,0,50);
}
$subject = ereg_replace("<","<",$subject);
$subject = ereg_replace(">",">",$subject);
if( strlen($subject) > 100 )
{
$subject = substr($subject,0,100);
}
$body = ereg_replace("<","<",$body);
$body = ereg_replace(">",">",$body);
$body = ereg_replace("\r\n","<br>",$body);
if( strlen($body) > 5000 )
{
$body = substr($body,0,5000);
}
//保存发言
fputs($handle,"$name||bbs||$email||bbs||$subject||bbs||$body||bbs||".
date("Y年m月d日 H:i"));
fclose($handle);
4 回复的分级保存
//方法和发言基本相同,只是增加了一些判断
//请注意 $filename传递的是发言的文件名
// 可是是标题文件名 1.txt
// 也可能是回复文件名 13_3_2.txt 第13个发言标题的第3个回复的第3个回复
//查找已经有的最大回复
for($i=1;$i<999999;$i++)
{
if(!file_exists($filename."_".$i))
{
break;
}
}
//找到,建立新的回复文件
//后面的与发言相同
fclose(fopen($filename."_".$i,"w"));
unlink("reply.tmp");
$handle = fopen($filename."_".$i,"w");
$name = ereg_replace("<","<",$name);
$name = ereg_replace(">",">",$name);
if( strlen($name) > 20 )
{
$name = substr($name,0,20);
}
$email = ereg_replace("<","<",$email);
$email = ereg_replace(">",">",$email);
if( strlen($email) > 50 )
{
$email = substr($email,0,50);
}
$subject = ereg_replace("<","<",$subject);
$subject = ereg_replace(">",">",$subject);
if( strlen($subject) > 50 )
{
$subject = substr($subject,0,50);
}
$body = ereg_replace("<","<",$body);
$body = ereg_replace(">",">",$body);
$body = ereg_replace("\r\n","<br>",$body);
if( strlen($body) > 500 )
{
$body = substr($body,0,500);
}
fputs($handle,"$name||bbs||$email||bbs||$subject||bbs||$body||bbs||".
date("Y年m月d日 H:i"));
fclose($handle);
