प्रत्येक पृष्ठ अनुरोध बस अपनी अंतिम गतिविधि को अपडेट करें।
<?php
mysql_query("UPDATE users SET lastactivity = ".time()." WHERE id = ".$userID);
यह दिखाने के लिए कि वे पिछली बार कब ऑनलाइन थे, बस डेटाबेस से उनकी अंतिम गतिविधि फ़ील्ड चुनें और उसे दिखाएं
<?php
$activity = mysql_result(mysql_query("SELECT lastactivity FROM users WHERE id = ".$userID), 0);
echo "Last activity: ".relativeTime($active);
जहां relativeTime()
वह फ़ंक्शन है जिसका मैं उपयोग कर रहा हूं:
function relativeTime($time, $short = false){
$SECOND = 1;
$MINUTE = 60 * $SECOND;
$HOUR = 60 * $MINUTE;
$DAY = 24 * $HOUR;
$MONTH = 30 * $DAY;
$before = time() - $time;
if ($before < 0)
{
return "not yet";
}

if ($before < 1 * $MINUTE)
{
return ($before <5) ? "just now" : $before . " ago";
}
