I am new to PHP and spent a few nights writing a message board. Please correct me
p.s. My space does not support PHP and I cannot provide a demonstration T_T
Database structure: (Library name: lyb)
Table 1: admin
field: id(int11) name(varchvr) password(varchvr)
Table 2: lo
field: id(int11) username(varchvr) sex(varchvr) qq(varchvr) email(varchvr) info(text) ip(varchvr) submit_time(datetime)
1 conn.php (connect database file)
mysql_connect("localhost"," root","");//Connect to the database
mysql_select_db("lyb");//Select the database
?>
2 header.php (public header file)
< body>
🎜> ;I want to publish
($_SESSION["key"]==1){//If the obtained SESSION is 1, the management item will be displayed
? Exit management
?>
.php">Occasional management
id="head_r">Silver Message Board Version 1.0
3 footer.php (public bottom file)
Copy code
The code is as follows:
$counterFile="conter.xml";
function displayCounter($counterFile){
$fp = fopen($counterFile,"rw");
$num = fgets($fp,5);
$num += 1;
print "";
exec("rm -rf $counterFile");
exec("echo $num > $counterFile");
}
if(!file_exists($counterFile)){
exec("echo 0 > $counterFile");
}
displayCounter($counterFile);
?>
🎜> The code is as follows:
require_once("conn.php");
require_once("header.php");
session_start();
//分页代码开始
$pagesize = 10;//设置每页显示条数
$rs = mysql_query("select count(*) from lo");//取得记录总数，计算总页数用
$myrow = mysql_fetch_array($rs);
$numrows = $myrow[0];//计算总记录
$pages = intval($numrows/$pagesize);
if($numrows%$pagesize)$pages++;//设置页数
if(isset($_GET['page']))
{
$page = intval($_GET['page']);
}
else
{
$page = 1;//设为第一页
}
$offset = $pagesize*($page-1);//计算记录偏移量
//分页代码结束
$sql = "select id,username,sex,qq,email,info,ip,DATE_FORMAT(submit_time, '%Y年%m月%d日 %T' ) from lo order by id desc limit $offset,$pagesize";//用到了DATE-FORMAT格式化日期格式
$result = mysql_query($sql);
$num = mysql_num_rows($result);
if($num>0){
while($row = mysql_fetch_array($result))
{
//echo print_r($row);
if($row[2]=="男")//这个使性别改成你想要的名称^_^
{
