What are some best practices for analyzing and interpreting data collected from user tracking in PHP?

Issue: When analyzing and interpreting data collected from user tracking in PHP, it is important to properly sanitize and validate the data to prevent SQL injection attacks and ensure the accuracy of the analysis. 

// Example of sanitizing and validating user tracking data in PHP
$user_id = $_POST['user_id']; // Assuming user_id is collected from a form submission
$user_id = filter_var($user_id, FILTER_SANITIZE_NUMBER_INT); // Sanitize user_id as an integer
if(filter_var($user_id, FILTER_VALIDATE_INT)) {
    // Proceed with analyzing and interpreting the user tracking data
} else {
    // Handle invalid user_id input
    echo "Invalid user ID provided";
}
