What are the potential drawbacks of relying on ping tests to measure website uptime?

Relying solely on ping tests to measure website uptime may not provide an accurate representation of the website's availability as ping tests only check if the server is reachable, not necessarily if the website is functioning properly. To ensure a more comprehensive measurement of website uptime, it is recommended to also perform HTTP status code checks or content checks to verify that the website is functioning as expected. 

// Example code snippet to check website uptime using HTTP status code check

$url = 'http://www.example.com';
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($handle);
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);

if ($httpCode == 200) {
    echo "Website is up";
} else {
    echo "Website is down";
}

curl_close($handle);
