How can PHP developers ensure that the message body is not empty when using PHPMailer?

To ensure that the message body is not empty when using PHPMailer, PHP developers can check if the message body is empty before sending the email. This can be done by validating the message body input and displaying an error message if it is empty. 

// Check if the message body is not empty
if (!empty($_POST['message'])) {
    // Initialize PHPMailer
    $mail = new PHPMailer();
    
    // Set message body
    $mail->Body = $_POST['message'];
    
    // Send email
    $mail->send();
} else {
    echo "Message body cannot be empty.";
}
