PHP: Send Mail with Attachment

By Xah Lee. Date: ,

This page shows you how to send email with attached file, using PHP.

Sending email in php is extremely easy. All you have to do is call the “mail” function. But how do you send out email with attachment?

There are php packages that allows you to do that, however, they will often need installation of the package, and if you are using a web hosting service provider, sometimes that is not possible. Luckily, it is not difficult to write a simple code that does it. All you have to do is to encode your mail payload as multipart MIME.

Here's a simple working example of sending html mail with attached file:


$fromAddr = ''; // the address to show in From field.
$recipientAddr = '';
$subjectStr = 'Thank you';

$mailBodyText = <<<END89283
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
<title>Thank You</title>
<b>Login:</b> {$_POST['login']}<br>
<b>Password:</b> {$_POST['password']}<br>

$filePath = 'uploaded_files/great_house.jpg';
$fileName = basename($filePath);
$fileType = 'image/jpeg';
/* to find out what string to use for type, see 
or $_FILES['attachment']['type'];

/* encode the email content */


From: $fromAddr
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="$mineBoundaryStr"


// Add a multipart boundary above the plain message 
$mailBodyEncodedText = <<<TTTTTTTTTTTTTTTTT
This is a multi-part message in MIME format.

Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable



$file = fopen($filePath,'rb'); 
$data = fread($file,filesize($filePath)); 
$data = chunk_split(base64_encode($data));

// file attachment part
$mailBodyEncodedText .= <<<FFFFFFFFFFFFFFFFFFFFF
Content-Type: $fileType;
Content-Disposition: attachment;
Content-Transfer-Encoding: base64




if (
mail( $recipientAddr , $subjectStr , $mailBodyEncodedText, $headers )
) {
  echo '<p>Send successfully!</p>';
} else {
  echo '<p>Bah!</p>';
