Show current number online

Introduced:

We can use the program to display the current data.

Focus on two points: 1. The following code must be placed in a file with a. php extension, 2. Your server must support the MySQL database when running code on your server.

The code is as follows:

The following code is placed where you want to display the information.

<?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");

}

?>

Finally, modify your username and passwords in MySQL
