What is the potential issue with using a do-while loop to send a newsletter to multiple recipients in PHP?

The potential issue with using a do-while loop to send a newsletter to multiple recipients in PHP is that if there is an error in sending the newsletter to one recipient, the loop will continue to execute, potentially sending duplicate emails or causing other issues. To solve this issue, it is better to use a foreach loop to iterate over the list of recipients and send the newsletter to each recipient individually. 

$recipients = ['recipient1@example.com', 'recipient2@example.com', 'recipient3@example.com'];

foreach ($recipients as $recipient) {
    // Send newsletter to $recipient
    // Add your code to send the newsletter here
}
