    $headers = "From: webmaster@mysite.com\r\nReply-To: ".$to;
    $headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
    $attachment = chunk_split(base64_encode(file_get_contents($pathToFilename)));
    ob_start();
    echo "
                --PHP-mixed-$random_hash
                Content-Type: multipart/alternative; boundary=\"PHP-alt-$random_hash\"

I have managed to debug my code, sorry for duplicate posting. It may help someone thanks

// Email to Client with attachement
                //define the receiver of the email
                $to = 'dibeesh@amt.in';

                $subject = 'Bayern3 Notification';

                //create a boundary string. It must be unique
                //so we use the MD5 algorithm to generate a random hash
                $random_hash = md5(date('r', time()));
                //define the headers we want passed. Note that they are separated with \r\n
                $headers = "From: lal@amt.in\r\nReply-To: dibeesh@amt.in";
                //add boundary string and mime type specification
                $headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
