[英]PHP - Don't Count Users from index.php
我有一個基本的在線訪客計數器。 我從這里得到的。 它運行很好,但是我有一個問題。 我在在線游戲上使用它,並且有多個服務器。 我將其用於服務器在線計數器。 我確實通過iframe將計數器頁面添加到服務器,並且計數非常好。
但是問題是,我想在索引(index.php)頁面上顯示該數字。 但是當我使用時:
<?php include("server1.php");?>
它也計算索引頁面用戶。 我不要這個 如何使它不計算來自index.php的IP?
在這里,我的密碼
計數器(server1.php)
<?php
$dbfile = "game/database/1.db"; // path to data file
$expire = 100; // average time in seconds to consider someone online before removing from the list
if(!file_exists($dbfile)) {
die("Error: Data file " . $dbfile . " NOT FOUND!");
}
if(!is_writable($dbfile)) {
die("Error: Data file " . $dbfile . " is NOT writable! Please CHMOD it to 666!");
}
function CountVisitors() {
global $dbfile, $expire;
$cur_ip = getIP();
$cur_time = time();
$dbary_new = array();
$dbary = unserialize(file_get_contents($dbfile));
if(is_array($dbary)) {
while(list($user_ip, $user_time) = each($dbary)) {
if(($user_ip != $cur_ip) && (($user_time + $expire) > $cur_time)) {
$dbary_new[$user_ip] = $user_time;
}
}
}
$dbary_new[$cur_ip] = $cur_time; // add record for current user
$fp = fopen($dbfile, "w");
fputs($fp, serialize($dbary_new));
fclose($fp);
$out = sprintf("%03d", count($dbary_new)); // format the result to display 3 digits with leading 0's
return $out;
}
function getIP() {
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
elseif(isset($_SERVER['REMOTE_ADDR'])) $ip = $_SERVER['REMOTE_ADDR'];
else $ip = "0";
return $ip;
}
$visitors_online = '0'+CountVisitors();
?>
<?=$visitors_online;?>
iframe(我在服務器頁面上使用它)
<iframe name="visitors" src="../1.php" width="1" hidden="true" height="1" frameborder="0" scrolling="no"></iframe>
php include(index.php)
Server 7 - Online Players:<?php include("7.php");?>
用此代碼制作server2.php
<?php
$dbfile = "game/database/1.db"; // path to data file
$expire = 100;
if(!file_exists($dbfile)) {
die("Error: Data file " . $dbfile . " NOT FOUND!");
}
if(!is_writable($dbfile)) {
die("Error: Data file " . $dbfile . " is NOT writable! Please CHMOD it to 666!");
}
function CountVisitors() {
global $dbfile, $expire;
$cur_time = time();
$dbary_new = array();
$dbary = unserialize(file_get_contents($dbfile));
if(is_array($dbary)) {
while(list($user_ip, $user_time) = each($dbary)) {
if(($user_time + $expire) > $cur_time) {
$dbary_new[$user_ip] = $user_time;
}
}
}
$out = sprintf("%03d", count($dbary_new)); // format the result to display 3 digits with leading 0's
return $out;
}
$visitors_online = '0'+CountVisitors();
?>
<?=$visitors_online;?>
並像server1.php一樣使用它
