Informations about the package mapi
Hfig/MAPI
Introduction
Hfig/MAPI
is a PHP library for reading and working with Microsoft Outlook/Exchange format email messages (.msg
files, aka MAPI documents).
The library can parse MAPI documents, and programatically extract the properties and streams of the document.
It can be used to convert messages to RFC822
(MIME) format by utilising the Swiftmailer/Switfmailer
library.
The library is ostensibly a port of the aquasync/ruby-msg
library from the Ruby language. Some questionable PHP architectural decisions come from migrating Ruby constructs. Some awful, but functional, code comes from a direct migration of the Ruby library.
Compared to ruby-msg
, this library:
- Does not implement a command line entry point for message conversion
- Only handles MAPI documents in
.msg
files (or a PHP stream of.msg
file data) - Does not implement the conversion of RTF-format message bodies to plain text or HTML
- Has better support for decoding MAPI document properties
- Produces a more faithful MIME conversion of the MAPI document
Installation
Install using composer
Usage
Accessing document properties
Conversion to MIME
Property Names
MAPI property names are documented by Microsoft in an inscrutible manner at https://docs.microsoft.com/en-us/previous-versions/office/developer/office-2007/cc815517(v%3doffice.12).
A list of property names available for use in this library is included in the MAPI/Schema/MapiFieldsMessage.yaml
file.
Keeping with the convention of the ruby-msg
library, message properties are converted to a nice name:
PR_DISPLAY_NAME
=>display_name
PR_ATTACH_FILENAME
=>attach_filename
- etc
About MAPI Documents
MAPI documents are Microsoft OLE Structured Storage databases, much like old .doc
, .xls
and .ppt
files. They consist of an internal directory structure of streams of 4K blocks that resemble a virtual FAT filesystem. For economy reasons, every structured storage database contains a root stream which contains 64-byte blocks which in turn stores small pieces of data. For further information see Microsoft's documentation.
The PEAR library OLE
can read these database files. However this PEAR library is ancient and does not meet any modern coding standards, hence it's kept entirely decoupled from the message parsing code of this library. Hopefully it can be replaced one day.
Alternatives
For PHP, installing the Kopano Core project on your server will make available ext-mapi
, a PHP extension which implements allows access to a port of the low-level MAPI Win32 API.
