PHP - Sending messages with attachements
This one is little tricky. We need to form the message in a special way.
Our message will be divided in at least two parts, one for the message and one for the attachment.
This is a so called MULTIPART message.
These two parts need to be separated, so we need a BOUNDARY between them. We will form the message by reading the content of the attachment and then converting it so that it can be transfered by email.
In the following example, we will send an HTML message with an attachment.
<?php
// Reading file content
$FilePathName = "ATTACHMENT_PATH_FILENAME"; // e.g. /tmp/myapp/file.gz
$FileName = "JUST_ATTACHMENT_FILENAME"; // just file.gz
$FileHandle = fopen($FilePathName, "rb");
$FileContent = fread($FileHandle, filesize($FilePathName));
fclose($FileHandle);
// Encode file content
$AttachmentData = chunk_split(base64_encode($FileContent));
// Message text
$MsgHTMLPart = "
<html>
<head>
<title>HTML message with attachment</title>
</head>
<body>
<h2>Congratulation!</h2>
<p>You have just learned how to send a HTML message with attachment</p>
</body>
</html>
";
// Forming message
$Recepient = "somebody@somewhere";
$MsgSubject = "Message subject";
// You must set sender through message header
$MsgHeader = "From: Sender name<sender@server>\n";
// These two lines marks message as multipart
$MsgHeader .= "MIME-Version: 1.0\n";
$MsgHeader .= "Content-Type: multipart/mixed; boundary=\"—–NSD35F65YGsgrg3—–\"";
// First part begins
$MsgBody = "
——-NSD35F65YGsgrg3—–
Content-Type: text/html; charset=us-ascii
Content-Transfer-Encoding: 8bit\n";
$MsgBody .= $MsgHTMLPart;
// Second part begins
$MsgBody .= "
——-NSD35F65YGsgrg3—–
Content-Type: application/octet-stream; name=\"" . $FileName . "\"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=\"" . $FileName . "\"\n\n";
$MsgBody .= $AttachmentData;
// Message ends
$MsgBody .= "\n—–NSD35F65YGsgrg3——-\n";
// Sending message
mail($Recepient, $MsgSubject, $MsgBody, $MsgHeader);
?>
// Reading file content
$FilePathName = "ATTACHMENT_PATH_FILENAME"; // e.g. /tmp/myapp/file.gz
$FileName = "JUST_ATTACHMENT_FILENAME"; // just file.gz
