copied!<p>To send an email with attachment we need to use the multipart/mixed MIME type that specifies that mixed types will be included in the email. Moreover, we want to use multipart/alternative MIME type to send both plain-text and HTML version of the email.Have a look at the example:</p> <pre><code><?php //define the receiver of the email $to = 'youraddress@example.com'; //define the subject of the email $subject = 'Test email with attachment'; //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: webmaster@example.com\r\nReply-To: webmaster@example.com"; //add boundary string and mime type specification $headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\""; //read the atachment file contents into a string, //encode it with MIME base64, //and split it into smaller chunks $attachment = chunk_split(base64_encode(file_get_contents('attachment.zip'))); //define the body of the message. ob_start(); //Turn on output buffering ?> --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 //copy current buffer contents into $message variable and delete current output buffer $message = ob_get_clean(); //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed"; ?> </code></pre> <p>As you can see, sending an email with attachment is easy to accomplish. In the preceding example we have multipart/mixed MIME type, and inside it we have multipart/alternative MIME type that specifies two versions of the email. To include an attachment to our message, we read the data from the specified file into a string, encode it with base64, split it in smaller chunks to make sure that it matches the MIME specifications and then include it as an attachment.</p> <p>Taken from <a href="http://webcheatsheet.com/php/send_email_text_html_attachment.php">here</a>.</p>
