What are common reasons for a PHP server status display showing "offline" when the server is actually online?

One common reason for a PHP server status display showing "offline" when the server is actually online is incorrect server configuration settings or network issues. To solve this issue, you can check the server's network connection, ensure the correct server IP address and port are used in the PHP code, and verify that the server is running and accessible. 

<?php
$server_ip = '127.0.0.1'; // Update with the correct server IP address
$server_port = 80; // Update with the correct server port

$fp = @fsockopen($server_ip, $server_port, $errno, $errstr, 5);

if ($fp) {
    echo "Server is online";
    fclose($fp);
} else {
    echo "Server is offline";
}
?>
