介绍：
我们可以通过程序来显示当前的数据。
注意的两点：1.必须把下列代码放到扩展名为.PHP的文件中；2.在你的服务器上运行代码时，你的服务器必须支持MYSQL数据库。
代码如下：
下列代码放到你想显示信息的地方。
<?php
//EDIT THIS
＄server = "localhost";
＄db_user = "database username";
＄db_pass = "database password";
＄database = "database";
＄timeoutseconds = 300;
//STOP EDITING
＄timestamp = time();
＄timeout = ＄timestamp-＄timeoutseconds;
mysql_connect(＄server, ＄db_user, ＄db_pass);
＄insert = mysql_db_query(＄database, "INSERT INTO useronline VALUES
(@#＄timestamp@#,@#＄REMOTE_ADDR@#,@#＄PHP_SELF@#)");
if(!(＄insert)) {
print "Useronline Insert Failed > ";
}
＄delete = mysql_db_query(＄database, "DELETE FROM useronline WHERE timestamp<＄timeout");
if(!(＄delete)) {
print "Useronline Delete Failed > ";
}
＄result = mysql_db_query(＄database, "SELECT DISTINCT ip FROM useronline WHERE file=@#＄PHP_SELF@#");
if(!(＄result)) {
print "Useronline Select Error > ";
}
＄user = mysql_num_rows(＄result);
mysql_close();
if(＄user == 1) {
print("＄user\n");
} else {
print("＄user\n");
}
?>
最后在MYSQL中修改你的 username 和 passwords
注意：把＄应为半角
