How does the code snippet ensure that only entries within the last 2 hours are considered?

The code snippet can ensure that only entries within the last 2 hours are considered by comparing the timestamp of each entry with the current time and only processing those that fall within the 2-hour window. 

$current_time = time();
$two_hours_ago = $current_time - (2 * 60 * 60);

foreach ($entries as $entry) {
    $entry_time = strtotime($entry['timestamp']);
    if ($entry_time >= $two_hours_ago && $entry_time <= $current_time) {
        // Process the entry within the last 2 hours
    }
}
