Sending email with multiple attachments using PHP Script

Using mail() function we can send simple mail see simple mail() script.
We can also send multiple attachement using php code and using php mail() function
For this we have to use MIME extenstion

The example below shows how to send multiple attachements with mail.
We have to create one array of files which we want to send in attachement by brosing from interface.

Example:

<?php
 
    // array with filenames to be sent as attachment
    $files = array("file1.jpg","file2.pdf","file3.txt");

    // email fields: to, from, subject, and so on
    $to = "yourmail@mail.com";
    $from = "mymail@mail.com"; 
    $subject ="My subject"; 
    $message = "My message";
    $headers = "From: $from";

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

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

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

    // preparing attachments
    for($x=0;$x<count($files);$x++){
            $file = fopen($files[$x],"rb");
            $data = fread($file,filesize($files[$x]));
            fclose($file);
            $data = chunk_split(base64_encode($data));
            $message .= "Content-Type: {\"application/octet-stream\"};\n" .  

                        " name=\"$files[$x]\"\n" . 
            "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
            "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
            $message .= "--{$mime_boundary}\n";
    }

    // send

    $success = @mail($to, $subject, $message, $headers); 
    if ($success) { 
            echo "<p>mail sent to $to!</p>"; 
    } else { 
            echo "<p>mail could not be sent!</p>"; 
    } 
 
?>
