# zbateson/mail-mime-parser

Testable and PSR-compliant mail mime parser alternative to PHP's imap* functions and Pear libraries for reading messages in _Internet Message Format_ [RFC 822](http://tools.ietf.org/html/rfc822) (and later revisions [RFC 2822](http://tools.ietf.org/html/rfc2822), [RFC 5322](http://tools.ietf.org/html/rfc5322)).

The goals of this project are to be:

* Well written
* Standards-compliant but forgiving
* Tested where possible

To include it for use in your project, please install via composer:

```
composer require zbateson/mail-mime-parser
```

## Deprecation Notice (since 1.2.1)

getContentResourceHandle, getTextResourceHandle, and getHtmlResourceHandle have all been deprecated due to #106. fread() will only return a single byte of a multibyte char, and so will cause potentially unexpected results/warnings in some cases, and psr7 streams should be used instead. Note that this deprecation doesn’t apply to getBinaryContentResourceHandle or getResourceHandle.

## Requirements

MailMimeParser requires PHP 5.4 or newer.  Tested on PHP 5.4, 5.5, 5.6, 7, 7.1, 7.2, 7.3 and 7.4 on travis.

Please note: hhvm support has been dropped as it no longer supports 'php' as of version 4.  Previous versions of hhvm may still work, but are no longer supported.

## Usage

```php
use ZBateson\MailMimeParser\MailMimeParser;
use ZBateson\MailMimeParser\Message;
use ZBateson\MailMimeParser\Header\HeaderConsts;

// use an instance of MailMimeParser as a class dependency
$mailParser = new MailMimeParser();

$handle = fopen('file.mime', 'r');
// parse() accepts a string, resource or Psr7 StreamInterface
$message = $mailParser->parse($handle);         // returns `Message`
fclose($handle);

// OR: use this procedurally (Message::from also accepts a string,
// resource or Psr7 StreamInterface
$message = Message::from($string);

echo $message->getHeaderValue(HeaderConsts::FROM);     // user@example.com
echo $message
    ->getHeader(HeaderConsts::FROM)                    // AddressHeader
    ->getPersonName();                                 // Person Name
echo $message->getHeaderValue(HeaderConsts::SUBJECT);  // The email's subject
echo $message
    ->getHeader(HeaderConsts::TO)                      // also AddressHeader
    ->getAddresses()[0]                                // AddressPart
    ->getName();                                       // Person Name
echo $message
    ->getHeader(HeaderConsts::CC)                      // also AddressHeader
    ->getAddresses()[0]                                // AddressPart
    ->getEmail();                                      // user@example.com

echo $message->getTextContent();                       // or getHtmlContent()

echo $message->getHeader('X-Foo');                     // for custom or undocumented headers

$att = $message->getAttachmentPart(0);                 // first attachment
echo $att->getHeaderValue(HeaderConsts::CONTENT_TYPE); // e.g. "text/plain"
echo $att->getHeaderParameter(                         // value of "charset" part
    'content-type',
    'charset'
);
echo $att->getContent();                               // get the attached file's contents
$stream = $att->getContentStream();                    // the file is decoded automatically
$dest = \GuzzleHttp\Psr7\stream_for(
    fopen('my-file.ext')
);
\GuzzleHttp\Psr7\copy_to_stream(
    $stream, $dest
);
// OR: more simply if saving or copying to another stream
$att->saveContent('my-file.ext');               // writes to my-file.ext
$att->saveContent($stream);                     // copies to the stream
```
