How can PHP be utilized to differentiate between web traffic generated by Apache and FTP servers on a website?

To differentiate between web traffic generated by Apache and FTP servers on a website, you can utilize the `$_SERVER['SERVER_SOFTWARE']` variable in PHP. This variable contains information about the server software being used, allowing you to distinguish between Apache and FTP traffic. 

if (strpos($_SERVER['SERVER_SOFTWARE'], 'Apache') !== false) {
    echo 'This is web traffic generated by Apache server.';
} elseif (strpos($_SERVER['SERVER_SOFTWARE'], 'FTP') !== false) {
    echo 'This is web traffic generated by FTP server.';
} else {
    echo 'Unknown server software.';
}
