# php-mime-mail-parser
A fully tested mailparse extension wrapper for PHP 5.4+
A fully tested email parser for PHP 7.1+ (mailparse extension wrapper).
It's the most effective php email parser around in terms of performance, foreign character encoding, attachment handling, and ease of use.

The following versions of PHP are supported:
* PHP 5.4
* PHP 5.5
* PHP 5.6
* PHP 7
* HHVM
* PHP 7.1
* PHP 7.2
* PHP 7.3

| PHP 5.6 | php-mime-mail-parser 3.0.4 |
| PHP 7.0 | php-mime-mail-parser 3.0.4 |
Make sure you have the mailparse extension (http://php.net/manual/en/book.mailparse.php) properly installed. The command line `php -m | grep mailparse` need to return "mailparse".
### Install mailparse extension
#### Ubuntu, Debian & derivatives
```
sudo apt install php-cli php-mailparse
```
#### Others platforms
```
sudo apt install php-cli php-pear php-dev php-mbstring
pecl install mailparse
```
Make sure you have the mailparse extension (http://php.net/manual/en/book.mailparse.php) properly installed. The command line `php -m | grep mailparse` need to return "mailparse" else install it:
* PHP version > 7.0: mailparse
* PHP version < 7.0: mailparse 2.1.6
#### From source
Follow this steps to install mailparse:
* Compile in the temp folder the extension mailparse or mailparse-2.1.6 (workaround because pecl install doesn't work yet)
AAAAMMDD should be `php-config --extension-dir`
```
cd
pecl download mailparse
tar -xvf mailparse-3.0.2.tgz
cd mailparse-3.0.2/
git clone https://github.com/php/pecl-mail-mailparse.git
cd pecl-mail-mailparse
phpize
./configure
sed -i 's/#if\s!HAVE_MBSTRING/#ifndef MBFL_MBFILTER_H/' ./mailparse.c
make
sudo mv modules/mailparse.so /usr/lib/php/20160303/
```
* Add the extension mailparse and activate it
```
sudo mv modules/mailparse.so /usr/lib/php/AAAAMMDD/
echo "extension=mailparse.so" | sudo tee /etc/php/7.1/mods-available/mailparse.ini
sudo phpenmod mailparse
```
On Windows, you need to download mailparse DLL from http://pecl.php.net/package/mailparse and add the line "extension=php_mailparse.dll" to php.ini accordingly.
#### Windows
You need to download mailparse DLL from http://pecl.php.net/package/mailparse and add the line "extension=php_mailparse.dll" to php.ini accordingly.
## How do I use it?
### Loading an email
You can load an email with 4 differents ways. You only need to use one of the following four.
```php
<?php
// Include the library first
require_once __DIR__.'/vendor/autoload.php';
$path = 'path/to/mail.txt';
$Parser = new PhpMimeMailParser\Parser();
$path = 'path/to/email.eml';
$parser = new PhpMimeMailParser\Parser();
// There are four methods available to indicate which mime mail to parse.
// You only need to use one of the following four:
// 1. Specify a file path (string)
$parser->setPath($path);
// 1. Specify a file path to the mime mail.
$Parser->setPath($path);
// 2. Specify the raw mime mail text (string)
$parser->setText(file_get_contents($path));
// 2. Specify a php file resource (stream) to the mime mail.
$Parser->setStream(fopen($path, "r"));
// 3. Specify a php file resource (stream)
$parser->setStream(fopen($path, "r"));
// 3. Specify the raw mime mail text.
$Parser->setText(file_get_contents($path));
// 4. Specify a stream to work with mail server
$Parser->setStream(fopen("php://stdin", "r"));
// Once we've indicated where to find the mail, we can parse out the data
$to = $Parser->getHeader('to'); // "test" <test@example.com>, "test2" <test2@example.com>
$addressesTo = $Parser->getAddresses('to'); //Return an array : [["display"=>"test", "address"=>"test@example.com", false],["display"=>"test2", "address"=>"test2@example.com", false]]
$from = $Parser->getHeader('from'); // "test" <test@example.com>
$addressesFrom = $Parser->getAddresses('from'); //Return an array : [["display"=>"test", "address"=>"test@example.com", "is_group"=>false]]
$subject = $Parser->getHeader('subject');
$text = $Parser->getMessageBody('text');
$html = $Parser->getMessageBody('html');
$htmlEmbedded = $Parser->getMessageBody('htmlEmbedded'); //HTML Body included data
$stringHeaders = $Parser->getHeadersRaw(); // Get all headers as a string, no charset conversion
$arrayHeaders = $Parser->getHeaders(); // Get all headers as an array, with charset conversion
// Pass in a writeable path to save attachments
$attach_dir = '/path/to/save/attachments/'; // Be sure to include the trailing slash
$include_inline = true; // Optional argument to include inline attachments (default: true)
$Parser->saveAttachments($attach_dir [,$include_inline]);
// Get an array of Attachment items from $Parser
$attachments = $Parser->getAttachments([$include_inline]);
// Loop through all the Attachments
if (count($attachments) > 0) {
foreach ($attachments as $attachment) {
echo 'Filename : '.$attachment->getFilename().'<br />'; // logo.jpg
echo 'Filesize : '.filesize($attach_dir.$attachment->getFilename()).'<br />'; // 1000
echo 'Filetype : '.$attachment->getContentType().'<br />'; // image/jpeg
echo 'MIME part string : '.$attachment->getMimePartStr().'<br />'; // (the whole MIME part of the attachment)
}
}
?>
// 4. Specify a stream to work with mail server (stream)
$parser->setStream(fopen("php://stdin", "r"));
```
### Get the metadata of the message
Get the sender and the receiver:
```php
$rawHeaderTo = $parser->getHeader('to');
// return "test" <test@example.com>, "test2" <test2@example.com>
$arrayHeaderTo = $parser->getAddresses('to');
// return [["display"=>"test", "address"=>"test@example.com", false]]
$rawHeaderFrom = $parser->getHeader('from');
// return "test" <test@example.com>
$arrayHeaderFrom = $parser->getAddresses('from');
// return [["display"=>"test", "address"=>"test@example.com", "is_group"=>false]]
```
Get the subject:
```php
$subject = $parser->getHeader('subject');
```
Get other headers:
```php
$stringHeaders = $parser->getHeadersRaw();
// return all headers as a string, no charset conversion
$arrayHeaders = $parser->getHeaders();
// return all headers as an array, with charset conversion
```
### Get the body of the message
```php
$text = $parser->getMessageBody('text');
// return the text version
$html = $parser->getMessageBody('html');
// return the html version
$htmlEmbedded = $parser->getMessageBody('htmlEmbedded');
// return the html version with the embedded contents like images
```
### Get attachments
Save all attachments in a directory
```php
$parser->saveAttachments('/path/to/save/attachments/');
// return all attachments saved in the directory (include inline attachments)
$parser->saveAttachments('/path/to/save/attachments/', false);
// return all attachments saved in the directory (exclude inline attachments)
// Save all attachments with the strategy ATTACHMENT_DUPLICATE_SUFFIX (default)
$parser->saveAttachments('/path/to/save/attachments/', false, Parser::ATTACHMENT_DUPLICATE_SUFFIX);
// return all attachments saved in the directory: logo.jpg, logo_1.jpg, ..., logo_100.jpg, YY34UFHBJ.jpg
// Save all attachments with the strategy ATTACHMENT_RANDOM_FILENAME
$parser->saveAttachments('/path/to/save/attachments/', false, Parser::ATTACHMENT_RANDOM_FILENAME);
// return all attachments saved in the directory: YY34UFHBJ.jpg and F98DBZ9FZF.jpg
// Save all attachments with the strategy ATTACHMENT_DUPLICATE_THROW
$parser->saveAttachments('/path/to/save/attachments/', false, Parser::ATTACHMENT_DUPLICATE_THROW);
// return an exception when there is attachments duplicate.
```
Get all attachments
```php
$attachments = $parser->getAttachments();
// return an array of all attachments (include inline attachments)
$attachments = $parser->getAttachments(false);
// return an array of all attachments (exclude inline attachments)
```
Loop through all the Attachments
```php
foreach ($attachments as $attachment) {
echo 'Filename : '.$attachment->getFilename().'<br />';
// return logo.jpg
echo 'Filesize : '.filesize($attach_dir.$attachment->getFilename()).'<br />';
// return 1000
echo 'Filetype : '.$attachment->getContentType().'<br />';
// return image/jpeg
echo 'MIME part string : '.$attachment->getMimePartStr().'<br />';
// return the whole MIME part of the attachment
$attachment->save('/path/to/save/myattachment/', Parser::ATTACHMENT_DUPLICATE_SUFFIX);
// return the path and the filename saved (same strategy available than saveAttachments)
}
```
## Postfix configuration to manage email from a mail server
Next you need to forward emails to this script above. For that I'm using [Postfix](http://www.postfix.org/) like a mail server, you need to configure /etc/postfix/master.cf
