What are some best practices for error handling when sending data to a server using stream_socket_client() in PHP?

When sending data to a server using `stream_socket_client()` in PHP, it is important to handle errors gracefully to ensure the stability and reliability of the application. One best practice is to check for errors using `stream_get_meta_data()` after attempting to establish the connection. This allows you to detect any connection issues and take appropriate action, such as logging the error or displaying a message to the user. 

$socket = stream_socket_client('tcp://example.com:80', $errno, $errstr, 30);

if (!$socket) {
    $metadata = stream_get_meta_data($socket);
    
    if ($metadata['timed_out']) {
        echo 'Connection timed out';
    } else {
        echo 'Error connecting to server: ' . $errstr;
    }
} else {
    // Send data to the server
    fwrite($socket, 'Hello, server!');
    
    // Close the connection
    fclose($socket);
}
