How can the issue of additional ATT000XX.txt files be resolved when sending attachments in PHP?

The issue of additional ATT000XX.txt files appearing when sending attachments in PHP can be resolved by setting the correct Content-Type and Content-Disposition headers in the email. By specifying the correct headers, the email client will recognize the attachment properly without creating additional text files. 

// Set the headers for the attachment
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/plain;charset=UTF-8" . "\r\n";
$headers .= "Content-Disposition: attachment; filename=\"filename.pdf\"" . "\r\n";

// Send the email with attachment
$to = "recipient@example.com";
$subject = "Attachment Test";
$message = "Please see the attached file.";
$attachment = chunk_split(base64_encode(file_get_contents("path/to/file.pdf")));
$from = "sender@example.com";

// Send email
$success = mail($to, $subject, $message, $headers, "-f" . $from);
if($success) {
    echo "Email sent successfully with attachment.";
} else {
    echo "Failed to send email with attachment.";
}
