我是靠谱客的博主仁爱树叶，最近开发中收集的这篇文章主要介绍BBS(php & mysql)完整版(一)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

//此页面为say.php
<?
include "signup/mysql.inc";
if($id1){
       $sql="select * from $table where id='$id1'";    //显示回复题目
       $result=mysql_query($sql)or die(mysql_error());
       $row=mysql_fetch_array($result);
       $title="RE:".$row["title"];

        }

$ip=$REMOTE_ADDR;
$sql="select * from user_stus where ip='$ip'";    //查询当前用户名
$result=mysql_query($sql)or die(mysql_error());
$row=mysql_fetch_array($result);

if(!$row)                                         //判断用户是否登陆
{

echo "<html><div id=Layer2  align=center z-index:1><BR><BR><BR><BR>";
echo" <div id=Layer3  align=center z-index:2><img src=pic/3.gif width=15 height=15></div>";
echo"  <div align=center>";
echo" <p><font size=2 color=#FF33CC>嘻嘻!! 请先登陆</font></p>";
echo"<p><font size=2 color=#FF33CC><a href='".$PHP_SELF."?p=1&&table=$table'>返回</a></font></p> </div> </html>";

exit();
}

else $userid=$row["userid"];

if($ok)
{

    if($title==""||$content=="")
    {
        echo "<BR>      请您添完整后提交";

    }
    else{
    $id=time();                                 //提交文章
    $date1=date("Y/m/d");
    $title=htmlspecialchars($title);
    $content=htmlspecialchars($content);

    $sql="select * from ".$table;
    $result=mysql_query($sql)or die(mysql_error());
    $row1=mysql_num_rows($result);
    $row1++;

    if($id1){

    $sql="insert into bbs_re (id,userid,date1,title,content)values('$id','$userid','$date1','$title','$content')";
    mysql_query($sql)or die(mysql_error());
    $sql="select * from ".$table." where id='$id1'";
    $result=mysql_query($sql)or die(mysql_error());
    $lin=mysql_fetch_array($result);
    for($i=1;$i<6;$i++)
        {
         $re="r".$i;
         if(!$lin["$re"])
         break;
        }
    $sql="update ".$table." set ".$re."='$id' where id='$id1'";

           }
    else
    $sql="insert into ".$table." (id,userid,date1,title,content,row)values('$id','$userid','$date1','$title','$content','$row1')";
    $result=mysql_query($sql)or die(mysql_error());

    if($result)
       {

        header("Location:php3.php?p=1&&table=$table");
        exit ;
       }
    }
