This PHP example script of a mail function let you send a plain text mail with one attached file. The file has to be uploaded first or should be an existing file on the web server. Of course there are better and more advanced scripts on the Internet, but I hope this script will help your to understand how things work. This script will show the (beginning) PHP developer how-to build their first e-mail script with attachment function. Please note that inside the mail function is no validation functionality.

<?php
function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message) {
    $file = $path.$filename;
    $file_size = filesize($file);
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    $content = chunk_split(base64_encode($content));
    $uid = md5(uniqid(time()));
    $name = basename($file);
    $header = "From: ".$from_name." <".$from_mail.">\r\n";
    $header .= "Reply-To: ".$replyto."\r\n";
    $header .= "MIME-Version: 1.0\r\n";
    $header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
    $header .= "This is a multi-part message in MIME format.\r\n";
    $header .= "--".$uid."\r\n";
    $header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
    $header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
    $header .= $message."\r\n\r\n";
    $header .= "--".$uid."\r\n";
    $header .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; // use different content types here
    $header .= "Content-Transfer-Encoding: base64\r\n";
    $header .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
    $header .= $content."\r\n\r\n";
    $header .= "--".$uid."--";
    if (mail($mailto, $subject, "", $header)) {
        echo = "mail send ... OK"; // or use booleans here
    } else {
        echo = "mail send ... ERROR!";
    }
}
?>

Next we show an example on how-to use this function to send an e-mail message with one attached zip file:

$my_file = "somefile.zip";
$my_path = $_SERVER['DOCUMENT_ROOT']."/your_path_here/";
$my_name = "Olaf Lederer";
$my_mail = "my@mail.com";
$my_replyto = "my_reply_to@mail.net";
$my_subject = "This is a mail with attachment.";
$my_message = "Hallo,\r\ndo you like this script? I hope it will help.\r\n\r\ngr. Olaf";
mail_attachment($my_file, $my_path, "recipient@mail.org", $my_mail, $my_name, $my_replyto, $my_subject, $my_message);

Hi Olaf,

I tried with your example. Mail sends with an attachment. But the size of attach zip file become 0 byte. So the zip file could not work.

I don't know whats the problem

Any help will be appreciated.

Thanks in advance,
Praveen

Hi,
maybe the path to the file is not right?

check this row first:
$my_path = $_SERVER['DOCUMENT_ROOT']."/your_path_here/";

maybe you need to use a static path?

Thanks for immediate reply

I checked the this row
$my_path = $_SERVER['DOCUMENT_ROOT']."/your_path_here/";

My directory structure is like this:
http://www.domain.com/foldername/zipfilename.zip

When I try with static link it gives warnings:

Warning: filesize() [function.filesize]: stat failed for http://www.domain.com/foldername/zipfilename.zip on line 191

Warning: fopen(www.domain.com/foldername/zipfilename.zip) [function.fopen]: failed to open stream: No such file or directory

Warning: fread(): supplied argument is not a valid stream resource

Warning: fclose(): supplied argument is not a valid stream resource
mail send ... OK

Any idea?

that's what I thought

A document root is something else, create a new file and check the doc root using:

echo $_SERVER['DOCUMENT_ROOT']

You need to learn what your document root is, this path is required to open a file with PHP.

create a new file and add this code:

<?php echo $_SERVER['DOCUMENT_ROOT']; ?>

Run this script in your browser, the result is the document root.

Next you need to check if this is confirm the place where the attachment is located.

when I run the above script on local system it prints "C:/xampp/htdocs"

And when I run the script on server it prints: "D:\Hosting\4836046\html"

my server directory structure is like this:
http://www.domain.com/foldername/zipfilename.zip

Windows server and document root are always a problem.

I never used PHP on windows, check this PHP function (and read the comments)
http://php.net/manual/en/function.getcwd.php

maybe that your hosting provider know how to identify the doc root from your account?

Ok I understood the problem. I will ask my service provider.

But the mail I am getting this time is containing the 0 bytes zip file attachment. Is this problem because of doc root?
