What are some best practices for testing a counterscript in PHP to ensure accurate tracking of website traffic?

When testing a counterscript in PHP to ensure accurate tracking of website traffic, it is important to simulate various scenarios to verify that the script is functioning correctly. This can include testing the script with different browsers, devices, and user behaviors to ensure accurate tracking of visits, pageviews, and unique visitors. 

// Sample PHP counterscript for tracking website traffic

// Function to increment visit count
function incrementVisitCount() {
    $countFile = 'visit_count.txt';
    $currentCount = (int)file_get_contents($countFile);
    $currentCount++;
    file_put_contents($countFile, $currentCount);
}

// Function to get total visit count
function getTotalVisitCount() {
    $countFile = 'visit_count.txt';
    return (int)file_get_contents($countFile);
}

// Increment visit count on page load
incrementVisitCount();

// Display total visit count
echo 'Total visits: ' . getTotalVisitCount();
