How can error handling be improved when using fsockopen in PHP to ensure proper timeout functionality?

When using fsockopen in PHP, it's important to properly handle errors and timeouts to ensure smooth functionality. One way to improve error handling is to set a timeout value for the fsockopen function. This can be achieved by using the stream_set_timeout function to specify the timeout duration in seconds. 

$socket = fsockopen($hostname, $port, $errno, $errstr, $timeout);
if (!$socket) {
    die("Error: $errstr ($errno)");
}

stream_set_timeout($socket, $timeout);

// Continue with socket operations
