PHPMailer - How do I unlink files in temp dir.? - phpmailer

Question

I am looping through the files array as shown in the middle chunk of code, rest of the code is just for better context.
$email = new PHPMailer();
$email->From = 'John#example.com';
$email->FromName = 'John Doe';
$email->Subject = $name_talent;
$body = '<strong>ADDRESS</strong> : ' .$address_talent.'<br><br>';
if ($_FILES) {
foreach ($_FILES as $file => $array) {
$tmp_path = $_FILES[$file]['tmp_name'];
$tmp_name = basename($_FILES[$file]['name']);
$email->AddAttachment($tmp_path, $tmp_name);
}
}
$email->Body = $body;
$email->IsHTML(true);
$email->AddAddress( '######gmail.com' );
$email->Send();
This sends the attachments with values in the $body as well. Now, I would like to unlink the files either after the mail is sent or the attachments are successful. As inspired from this answer, If I do it like this below, no files are attached and any variables set for the $body eg. $address_talent do not appear in the email.
if ($_FILES) {
foreach ($_FILES as $file => $array) {
$tmp_path = $_FILES[$file]['tmp_name'];
$tmp_name = basename($_FILES[$file]['name']);
if($email->AddAttachment($tmp_path, $tmp_name)){
unlink("$tmp_path");
}
}
}
