    substr() uses the string length, not the position as third argument. The corrected version of the following code line:
    <?php
    $parts    [$s] = substr($file_txt, $starting_pos_body, $ending_pos_body-$starting_pos_body);
    ?>

    Here a full example to save ZIP files attachments in their original name.

    <?php
    $email_raw     = '(raw e-mail contents buffer)';
    $parser = mailparse_msg_create(); // MUST be destroyed at the end of the script
    mailparse_msg_parse($parser, $email_raw);
    $structure = mailparse_msg_get_structure($parser); // Ex. ["1", "1.1", "1.2"]
    foreach ($structure as $part_label) { // Search among each e-mail part
            $part = mailparse_msg_get_part($parser, $part_label); // Parse a specified part
            $part_data = mailparse_msg_get_part_data($part); // Get parsed part data, header and meta values
            if ($part_data['content-type'] ?? null === 'application/zip') {
                $name = $part_data['disposition-filename'] ?? $part_data['content-name'] ?? 'unknow.zip';
                $contents = mailparse_msg_extract_part($part, $email_raw, null); // null for returning content
                file_put_contents($name, $contents);
        }
    }
    mailparse_msg_free($parser); // Important

    The callback argument does not support closures... :( It will complains with "PHP Catchable fatal error:  Object of class Closure could not be converted to string".

    With ref to previous comment re: callback:

    If you explicitly specify NULL as the callback parameter, the complete section is extracted, decoded and returned, without the need for a callback.

    In mailparse version 2.1.1 (and perhaps earlier), when using mailparse_msg_extract_part() with a callback function, it breaks the data it passes to it into 4kB chunks and calls the callback function for each chunk.  So, for example, if it's extracting a 41kB MIME part, the callback function you define will be called 11 times, each time with the next chunk of data.  Here's some quick-and-dirty code that shows one way to handle this:

    <?php
        $message     = file_get_contents ("email.txt"); // Pull in the e-mail.

            function catch_part ($part)
        {
                $GLOBALS["part_data"] .= $part; // Append the data onto any previously extracted data.
            }

            mailparse_msg_extract_part ("1.1", $message, "catch_part"); // Extract MIME part 1.1
            echo $GLOBALS["part_data"]; // Print out the extracted part.
    ?>

    There's probably a much better way of dealing with this, but hey.  It's what I got.

    Unless I've missed something obvious:

    get_structure returns array(1,1.1,1.1.2) etc but its not easy to get the contents of each part as mailparse_msg_extract_part() and mailparse_msg_extract_part_file() just return the lot.  However get_part_data will return the string offsets so you know where to chop the message so you can get the contents of the parts.

    Only issue is get_part_data returns:
        [starting-pos] => 0
        [starting-pos-body] => 1412
        [ending-pos] => 14989
        [ending-pos-body] => 14989

    Unless I'm missed something else, theres a bug here as ending-pos is the same as ending-pos-body so it won't chop the contents cleanly, leaving the:

    ------=_NextPart_000_0069_01C659A6.9072E590--

    ...as supposedly part of the section contents.

    $file = "..../mail"; // path of your mail
    $file_txt = implode("",file($file));
    $parse = mailparse_msg_parse_file($file);
    $structure = mailparse_msg_get_structure($parse);
    // chop message parts into array
    $parts = array();
    foreach ($structure as $s){
        print "Part $s\n";
        print "--------------------------------------\n";
        $part = mailparse_msg_get_part($parse, $s);
        $part_data = mailparse_msg_get_part_data($part);
        print_r($part_data);
        $starting_pos_body = $part_data['starting-pos-body'];
        $ending_pos_body    = $part_data['ending-pos-body'];
        $parts[$s] = substr($file_txt,$starting_pos_body,$ending_pos_body); // copy data into array
        print "[".$parts[$s]."]";
        print "\n------------------------------------\n";
    }
