Short answer: if your upload already works, hand the uploaded file (the tmp_name) to a mailer and let the library build the MIME parts. was right to recommend using a library; ’s raw mail() example shows how multipart MIME works but is easy to get wrong. For reliability and security use a maintained library (PHPMailer, Symfony Mailer, etc.) and send via SMTP rather than trying to craft boundaries yourself.

Quick checklist before attaching:

  • Verify the upload succeeded ($_FILES['file']['error'] === UPLOAD_ERR_OK and is_uploaded_file()).
  • Validate the file type with finfo_file() (do not trust $_FILES['file']['type']).
  • Enforce size limits and allowed extensions (compare against upload_max_filesize / post_max_size).
  • Sanitize the original filename ($name = basename($_FILES['file']['name']); and strip odd chars).
  • Use move_uploaded_file() if you want to keep a permanent copy; otherwise attach from the tmp_name immediately.

Example (PHPMailer) — attach the uploaded file by path:

use PHPMailer\PHPMailer\PHPMailer;
require 'vendor/autoload.php';

$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'smtp-user';
$mail->Password = 'smtp-pass';
$mail->setFrom('webmaster@example.com');
$mail->addAddress('admin@my');
$mail->Subject = 'Uploaded file';
$mail->Body = 'See attached';
$mail->addAttachment($_FILES['file']['tmp_name'], basename($_FILES['file']['name']));
if (! $mail->send()) {
    error_log('Mail error: ' . $mail->ErrorInfo);
}

Troubleshooting and cautions: attachments may be rejected if too large or if your server’s MTA (sendmail/postfix/exim) blocks them; check mail logs and SMTP debug output. Always sanitize filenames and validate MIME types; consider virus-scanning or quarantining uploads before emailing them. For PHP upload details see the official docs: PHP file upload basics. For a modern mail library see PHPMailer.

Hi Jacob, the easiest way would be to use some mailing library like XPertMailer http://www.xpertmailer.com/. It would take care of all the boring stuff related to sending attachments or html e-mails or validating e-mail addresses, or even protecting yourself from e-mail injection attack.

If you however, insist on implementing it yourself, here's a good tutorial:
http://www.webcheatsheet.com/PHP/send_email_text_html_attachment.php
It's the #1 hit in Google when you search for "send attachment php".

If you can't click the link provided and scroll down, here's the code it gives on emailing attachments(stripped of comments):

<?php
$to = 'youraddress@example.com';
$subject = 'Test email with attachment';
$random_hash = md5(date('r', time()));
$headers = "From: webmaster@example.com\r\nReply-To: webmaster@example.com";
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
$attachment = chunk_split(base64_encode(file_get_contents('attachment.zip')));
ob_start();
?>
--PHP-mixed-<?php echo $random_hash; ?> 
Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>"

--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

Hello World!!!
This is simple text email message.

--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit

<h2>Hello World!</h2>
<p>This is something with <b>HTML</b> formatting.</p>

--PHP-alt-<?php echo $random_hash; ?>--

--PHP-mixed-<?php echo $random_hash; ?> 
Content-Type: application/zip; name="attachment.zip" 
Content-Transfer-Encoding: base64 
Content-Disposition: attachment 

<?php echo $attachment; ?>
--PHP-mixed-<?php echo $random_hash; ?>--

<?php
$message = ob_get_clean();
$mail_sent = @mail( $to, $subject, $message, $headers );
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
