What is the purpose of marking a time window in a different color before reaching a database entry in PHP?

When marking a time window in a different color before reaching a database entry in PHP, the purpose is to visually distinguish the data within that specific time frame. This can help users easily identify and understand the data that falls within the designated time window.

// Assuming $entryTime is the timestamp of the database entry and $startTime and $endTime are the start and end times of the time window

if ($entryTime >= $startTime && $entryTime <= $endTime) {
    echo '<span style="color: blue;">'; // Apply blue color to entries within the time window
}

// Display the database entry here

if ($entryTime >= $startTime && $entryTime <= $endTime) {
    echo '</span>';
}
