What are some potential solutions for separating the process of saving data to a database and generating a PDF in PHP?

One potential solution is to use a queue system like RabbitMQ or Beanstalkd to separate the process of saving data to a database and generating a PDF in PHP. By decoupling these tasks, you can ensure that the data is saved successfully before generating the PDF, improving the overall reliability and performance of your application. 

// Code snippet using RabbitMQ to separate saving data and generating PDF
// Producer script to save data to database
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

$channel->queue_declare('save_data_queue', false, true, false, false);

$data = array('name' => 'John Doe', 'age' => 30); // Sample data to be saved

$msg = new AMQPMessage(json_encode($data));
$channel->basic_publish($msg, '', 'save_data_queue');

echo "Data saved to queue\n";

$channel->close();
$connection->close();

// Consumer script to generate PDF
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

$channel->queue_declare('save_data_queue', false, true, false, false);

$callback = function ($msg) {
    $data = json_decode($msg->body, true);

    // Generate PDF using $data

    echo "PDF generated\n";
};

$channel->basic_consume('save_data_queue', '', false, true, false, false, $callback);

while (count($channel->callbacks)) {
    $channel->wait();
}

$channel->close();
$connection->close();
