# Mail_mimeDecode::decode()

Mail_mimeDecode::decode() -- perform decoding

## Synopsis

    require_once 'Mail/mimeDecode.php';

``object decode` (array [$args = `NULL`])`

## Description

This function performs the decoding and returns a structure containing the message data.

## Parameter

- `array $args` - an array with the function arguments

  - `boolean $args['include_bodies']` - whether to include the bodies in the returned structure.

  - `boolean $args['decode_bodies']` - whether to decode the returned bodies.

  - `boolean $args['decode_headers']` - whether to decode the headers (RFC2047).

  - `string $args['input']` - if and only if called statically, this should be used to specify the input to be decoded.

  - `string $args['crlf']` - if and only if called statically, this should be used to specify the line ending type.

## Return value

`object` -

- `array $return->headers` - an associative array of the headers. The keys of the array are the header names (lowercased) whilst the values are the header values (original case). If there are multiple headers with the same name (eg. `Received:` ) then the value is a numerically indexed array of each of the header values. If the parameter `decode_headers` is specified as `TRUE`, the headers will be decoded according to RFC 2047.

- `string $return->ctype_primary` - the first part of the content type (ie. before the forward slash). Eg. if the content type is `multipart/mixed`, ctype_primary would be `"multipart"`.

- `string $return->ctype_secondary` - the second part of the content type. Eg. If the content type is `multipart/mixed`, ctype_secondary would be `"mixed"`.

- `array $return->ctype_parameters` - if the content type header has any parameters (eg. `boundary="=_hudfhdsalfhds8fy8329hfj`") then they will be in this associative array. Keys are the parameter name (eg. `boundary`) whilst the values are the parameter values (eg. =`_hudfhdsalfhds8fy8329hfj`).

- `string $return->disposition` - if the Content-Disposition header is present, its value will be given here. This is usually either `"inline"` or `"attachment"`.

- `array $return->d_parameters` - if any parameters are given with the Content-Disposition header, they will be given here in an associative array, keys being the parameter names and values being the parameter values. `"name"` and `"filename"` are two common examples here.

- `array $return->body` - if the `include_bodies` parameter is given when instanciating the class, (either statically or via a concrete instance), then this will be present if the part in question has a body. MIME parts with content type `multipart/*` generally do not not have bodies, instead consisting of subparts. If the parameter `decode_bodies` is specified as `TRUE` then the body will be decoded.

- `array $return->parts` - if a MIME part consists of subparts, then this array will be present consisting of objects with the same properties as described here.

Error code | Error message | Reason | Solution
--- | --- | --- | ---
`NULL` | " Called statically and no input given " | You called the function statically and forgot to fill `$args['input']` | Fill `$args['input']` with the content to decode or do not call the function statically.
`NULL` | every other | See the error message. | The input or parts of the input does not complies to the MIME standard.
