معرفی ادیتور html سبک

اين با session :

[PHP] <?php
session_start();
function getUsersOnline() {
$count = 0;
$handle = opendir(session_save_path());
if ($handle == false) return -1;
while (($file = readdir($handle)) != false) {
if (ereg("^sess", $file)) $count++;
}
closedir($handle);
return $count;
}
?>
[/PHP]

اينم با mysql :

كد هاي زير در mysql :

کد:

CREATE TABLE online_count ( ip char(15) NOT NULL, TMP timestamp(14), PRIMARY KEY (ip) );

اينها هم در فايل :
[PHP]
<?php $Host = "localhost"; //Host name $User = "root"; // Username $Mdp = "alvan"; // Password $Base = "test"; // Database Name mysql_connect ( $Host , $User , $Mdp ); //Timeout in seconds $TimeOut = 60; $ip = getenv( "REMOTE_ADDR" ); $Requete = "DELETE FROM online_count WHERE TMP < now()"; $Resultat = mysql_db_query( $Base , $Requete ); $Requete = "SELECT count(*) FROM online_count WHERE ip='$ip'"; $Resultat = mysql_db_query( $Base , $Requete ); while ( $T = @mysql_fetch_array( $Resultat ) ) { $Compteur = $T["count(*)"]; } if ( $Compteur ) { $Requete = "UPDATE online_count SET TMP=TMP + $TimeOut WHERE ip='$ip'"; } else { $Requete = "INSERT INTO online_count (ip, TMP) VALUES ('$ip', now()+ $TimeOut)"; } $Envoi = mysql_db_query( $Base , $Requete ); $Requete = "SELECT count(*) FROM online_count"; $Envoi = mysql_db_query( $Base , $Requete ); while ( $T = @mysql_fetch_array( $Envoi ) ) { $Compteur = $T["count(*)"]; } echo $Compteur; ?>
[/PHP]
