$from = "myname";
$subject = "Here is your attachment";
$mainMessage = "Hi, here's the file.";
$fileatt = $_SERVER['DOCUMENT_ROOT']."/xxx/ticket.pdf";
$fileatttype = "application/pdf";
$fileattname = "ticket.pdf";
$headers = "From: $from";
// File
$file = fopen($fileatt, 'rb');
$data = fread($file, filesize($fileatt));
fclose($file);
// This attaches the file
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$message = "This is a multi-part message in MIME format.\n\n" .
"-{$mime_boundary}\n" .
"Content-Type: text/html; charset=\"iso-8859-1\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$mainMessage . "\n\n";
$data = chunk_split(base64_encode($data));
$message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatttype};\n" .
" name=\"{$fileattname}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$fileattname}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"-{$mime_boundary}-\n";
// Send the email
if(mail($to, $subject, $message, $headers)) {

echo "There was an error sending the mail.";
}
?>

You can try this code:
$to = "youremail#gmail.com";
$from = "Myname <sender#gmail.com>";
$subject = "Test Attachment Email";
$separator = md5(time());
// carriage return type (we use a PHP end of line constant)
$eol = PHP_EOL;
// attachment name
$filename = "document.pdf";
//$pdfdoc is PDF generated by FPDF
$pdfdoc = "/opt/transmail/2018-03-07_32_11564_invoice.pdf";
$attachment = chunk_split(base64_encode($pdfdoc));
// main header
$headers = "From: ".$from.$eol;
$headers .= "MIME-Version: 1.0".$eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"";
// no more headers after this, we start the body! //
$message = "Thanks";
$body = "--".$separator.$eol;
$body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
$body .= "This is a MIME encoded message.".$eol;
// message
$body .= "--".$separator.$eol;
$body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
$body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$body .= $message.$eol;
// attachment
$body .= "--".$separator.$eol;
$body .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol;
$body .= "Content-Transfer-Encoding: base64".$eol;
$body .= "Content-Disposition: attachment".$eol.$eol;
$body .= $attachment.$eol;
$body .= "--".$separator."--";
// send message
if (mail($to, $subject, $body, $headers)) {
echo "mail send ... OK";
} else {
echo "mail send ... ERROR";
}
hope this will work for you.
