What are some common challenges or pitfalls when implementing a PHP stat tracker?

One common challenge when implementing a PHP stat tracker is ensuring accurate data collection, especially when dealing with high traffic websites. To address this, it's important to optimize database queries and consider using caching mechanisms to reduce server load. 

// Example of optimizing database query for stat tracking
$query = "SELECT COUNT(*) FROM page_views WHERE date = CURDATE()";
$result = $mysqli->query($query);
$row = $result->fetch_assoc();
$pageViewsToday = $row['COUNT(*)'];
