require_once "vendor/autoload.php"; use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; // Create a new PHPMailer object $mail = new PHPMailer(true); // Set up SMTP mail server $mail->isSMTP(); $mail->SMTPAuth = true; $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; $mail->Host = 'smtp.gmail.com'; $mail->Port = 587; $mail->Username = 'your_email@gmail.com'; $mail->Password = 'your_password'; // Set up email content $mail->setFrom('sender_email@example.com'); $mail->addAddress('recipient_email@example.com'); $mail->Subject = 'Testing AddEmbeddedImage'; $mail->Body = ''; // Add an embedded image to the email $imagePath = 'path/to/image.png'; $imageName = 'image1'; $imageType = 'image/png'; $mail->AddEmbeddedImage($imagePath, $imageName, $imageName, $imageType); // Send email if ($mail->send()) { echo 'Email sent successfully'; } else { echo 'Error: ' . $mail->ErrorInfo; }This code uses PHPMailer to send an email with an embedded image. The `AddEmbeddedImage()` function is used to add the image to the email and the `src` attribute of the `img` tag in the email body is set to `cid:image1`, which references the unique identifier of the embedded image. Based on the use of the `use` statements, it appears that this code is using the PHPMailer library version 6.0 or later, installed via Composer.
