介紹:
我們可以通過程序來顯示當前的數據。
注重的兩點:1.必須把下列代碼放到擴展名為.PHP的文件中;2.在你的服務器上運行代碼時,你的服務器必須支持MYSQL數據庫。
代碼如下:
下列代碼放到你想顯示信息的地方。
<?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($user == 1) {
print("$usern");
} else {
print("$usern");
}
?>
最後在MYSQL中修改你的 username 和 passwords
