try this code,
$filename = "file1.pdf";
$file = $path . "/" . $filename;
$message ="my message";
$file_size = filesize($file);
$handle = fopen($file, "r");
$content = fread($handle, $file_size);
fclose($handle);
$content = chunk_split(base64_encode($content));
// a random hash will be necessary to send mixed content
$separator = md5(time());
// carriage return type (we use a PHP end of line constant)
$eol = PHP_EOL;
// main header (multipart mandatory)
$headers = "From: name <test#test.com>" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol;
$headers .= "This is a MIME encoded message." . $eol;
// message
$headers .= "--" . $separator . $eol;
$headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
$headers .= "Content-Transfer-Encoding: 8bit" . $eol;
$headers .= $message . $eol;
// attachment
$headers .= "--" . $separator . $eol;
$headers .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: base64" . $eol;
$headers .= "Content-Disposition: attachment" . $eol;
$headers .= $content . $eol;
$headers .= "--" . $separator . "--";
//SEND Mail
if (mail($mailto, $subject, "", $headers)) {
echo "mail send ... OK"; // or use booleans here
} else {
echo "mail send ... ERROR!";
}
i hope it will be helpful.
