## Functions


### `@MIME.createMultipart()`


```code
@MIME.createMultipart(object $parts, string $boundary, string $preamble, string $epilog): string
```

##### Parameters

| Name | Type | Value | Default |
| --- | --- | --- | --- |
| parts | `object`  |  | [] |

| preamble | `string`  |  | "" |
| epilog | `string`  |  | "" |

##### Returns

| Type | Value |
| --- | ---  |
| `string` |  |




### `@MIME.fromBase64()`


Decodes a string according to RFC 2045 by converting printable characters back to arbitrary byte sequences.
