how can attach a file to email in php

attach a file to an email message

file attach to an email message,we have to create a multipart MIME message. -Pass these headers as the fourth parameter to mail(): MIME-Version: 1.0 Content-Type: multipart/mixed; boundary=”php-12345″ Note the boundary on the end of the Content-Type.The boundary is an arbitrary US-ASCII string that tells MUAs when the end of a MIME block has been reached. -The first part of the message string should be a plain text message.

Note the boundary marker after the message which tells MIME that we’ve reached the end of this particular part of the email message. -The second part of the “message string ” should be the message itself.We need to add Content-Type and Content-Transfer-Encoding headers to the message, followed by the message itself.

We have to put the boundary marker after at the end of each part of the message. -Next come the attachments. Each attachment gets added to the “message” string as well. We need to add Content-Type and Content-Transfer-Encoding headers, and then the attachment.


example of attach file through mail

<?php
$fileatt = ""; // Path to the file
$fileatt_type = "application/octet-stream"; // File Type
$fileatt_name = ""; // Filename that will be used for the file as the attachment

$email_from = ""; // Who the email is from
$email_subject = ""; // The Subject of the email
$email_txt = ""; // Message that the email has in it

$email_to = ""; // Who the email is too

$headers = "From: ".$email_from;

$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);

$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_message . "\n\n";

$data = chunk_split(base64_encode($data));

$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";

$ok = @mail($email_to, $email_subject, $email_message, $headers);

if($ok) {
echo "<font face=verdana size=2>The file was successfully sent!</font>";
} else {
die("Sorry but the email could not be sent. Please go back and try again!");
}
