Are there any potential pitfalls in using the ping command on the cmd level to check website availability?

One potential pitfall of using the ping command on the cmd level to check website availability is that some websites may block ICMP requests, rendering the ping command ineffective. To overcome this limitation, you can use PHP's built-in functions like `file_get_contents` or `curl` to check website availability by sending HTTP requests instead. 

<?php
function checkWebsiteAvailability($url) {
    $headers = @get_headers($url);
    if($headers && strpos($headers[0], '200')) {
        return "Website is available";
    } else {
        return "Website is not available";
    }
}

$url = "https://www.example.com";
echo checkWebsiteAvailability($url);
?>
