hi jegan,
Thanks for ur solution and Me too got another short following solution for the above problem,

$fileatt = "xxx.xxx"; // Path to the file
$fileatt_type = "application/octet-stream"; // File Type
$fileatt_name = "xxx.xxx"; // Filename that will be used for the file as the attachment

$email_from = "test@test.com"; // Who the email is from
$email_subject = "testing"; // The Subject of the email
$email_txt = "testing the test"; // Message that the email has in it
$email_mess = "message content";
$email_to = "xxxxxxx@xxxxx.com"; // Who the email is to send

$headers = "From: ".$email_from;

$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($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}\"";

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_mess . "\n\n";

$data = chunk_split(base64_encode($data));

$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n<br>";

$ok = @mail($email_to, $email_subject, $email_message, $headers);

if($ok) {
echo "<font face=verdana size=2>The file was successfully sent!</font>";
} else {
die("Sorry but the email could not be sent. Please go back and try again!");
}
