What are some simple ways to display the current traffic of a website using PHP?

To display the current traffic of a website using PHP, you can utilize a simple method such as storing the visitor count in a text file or database and incrementing it each time a visitor accesses the site. You can then retrieve and display this count on your website to show the current traffic.

// Increment visitor count
$visitor_count_file = 'visitor_count.txt';
$visitor_count = (file_exists($visitor_count_file)) ? file_get_contents($visitor_count_file) : 0;
$visitor_count++;
file_put_contents($visitor_count_file, $visitor_count);

// Display visitor count
echo 'Current Traffic: ' . $visitor_count;
