answer:Sure! Here's the same code with additional comments to explain each section: ``` // Load the PHPMailer library require 'phpmailer/PHPMailerAutoload.php'; // Create a new instance of PHPMailer mail = new PHPMailer; // Set the transport protocol to SMTP mail->isSMTP(); // Set the SMTP server address mail->Host = 'smtp.example.com'; // Enable SMTP authentication mail->SMTPAuth = true; // Set the SMTP username and password for authentication mail->Username = 'your_username'; mail->Password = 'your_password'; // Set the encryption protocol to be used for SMTP connection mail->SMTPSecure = 'tls'; // Set the SMTP port mail->Port = 587; // Set the "from" email address and name mail->setFrom('[email protected]', 'Mailer'); // Set the recipient email address and name mail->addAddress('[email protected]', 'Recipient'); // Set the "reply-to" email address and name mail->addReplyTo('[email protected]', 'Mailer'); // Set the subject line of the email mail->Subject = 'PHPMailer SMTP message'; // Set the body of the email mail->Body = 'This is a test email message sent from PHPMailer using SMTP protocol. '; // Send the email and check if it was successful if(!mail->send()) { // If the email failed to send, show an error message with the specific error information echo 'Message could not be sent. '; echo 'Mailer Error: ' . mail->ErrorInfo; } else { // If the email was sent successfully, show a success message echo 'Message has been sent'; } ``` I hope these comments help! Let me know if you have any further questions.

answer:To add multiple recipients to the email, you can use the `addAddress()` method multiple times. Here's an updated version of the code that includes two additional recipients: ``` require 'phpmailer/PHPMailerAutoload.php'; mail = new PHPMailer; mail->isSMTP(); mail->Host = 'smtp.example.com'; mail->SMTPAuth = true; mail->Username = 'your_username'; mail->Password = 'your_password'; mail->SMTPSecure = 'tls'; mail->Port = 587; mail->setFrom('[email protected]', 'Mailer'); // Add the first recipient mail->addAddress('[email protected]', 'Recipient 1'); // Add the second recipient mail->addAddress('[email protected]', 'Recipient 2'); // Add a reply-to address mail->addReplyTo('[email protected]', 'Mailer'); mail->Subject = 'PHPMailer SMTP message'; mail->Body = 'This is a test email message sent from PHPMailer using SMTP protocol. '; if(!mail->send()) { echo 'Message could not be sent. '; echo 'Mailer Error: ' . mail->ErrorInfo; } else { echo 'Message has been sent'; } ``` In this code, we've added two extra recipients by calling the `addAddress()` method twice, each time with a different email address and name. You can repeat this process to add as many recipients as you like. Note that adding a large number of recipients may slow down the email sending process.

answer:I do not have access to real-time information. However, according to the most recent statistics from the japan ministry of internal affairs and communications, the unemployment rate in tokyo was 2.4% in may 2021.

answer:Yes, of course! According to the same statistics, the national unemployment rate in Japan as of May 2021 was 3.0%. This means that the unemployment rate in Tokyo is lower than the national average.
