Are there any limitations or restrictions in XAMPP that may prevent establishing a connection to an external server using PHP sockets?

XAMPP may have restrictions on outgoing connections that could prevent establishing a connection to an external server using PHP sockets. To solve this issue, you can try configuring XAMPP to allow outgoing connections or use a different server environment that does not have these restrictions. 

// Example PHP code snippet to establish a connection to an external server using PHP sockets
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
    echo "Failed to create socket: " . socket_strerror(socket_last_error());
} else {
    $result = socket_connect($socket, 'example.com', 80);
    if ($result === false) {
        echo "Failed to connect to server: " . socket_strerror(socket_last_error($socket));
    } else {
        echo "Connected to server successfully!";
        // Perform further operations with the socket connection
        socket_close($socket);
    }
}
