How can changes in email service providers impact PHP email sending functionality?

When changing email service providers, the SMTP settings and authentication methods may differ, causing PHP email sending functionality to break. To fix this, update the PHP code to reflect the new SMTP settings and authentication requirements of the new email service provider. 

// Set the new SMTP settings and authentication for the new email service provider
$smtpHost = 'new_host';
$smtpUsername = 'new_username';
$smtpPassword = 'new_password';
$smtpPort = 587;

// Create a new PHPMailer instance and set the new SMTP settings
$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = $smtpHost;
$mail->SMTPAuth = true;
$mail->Username = $smtpUsername;
$mail->Password = $smtpPassword;
$mail->SMTPSecure = 'tls';
$mail->Port = $smtpPort;

// Send the email using the updated PHPMailer instance
$mail->send();
