Get plain text from Word [2003-2007], and Excel [2003-2007] files using PHP

What is the simplest way to get the plain-text only from filetypes: Word [2003-2007], and Excel [2003-2007], using PHP on a Windows Server 2008 machine?

Theoretically, I could use the indexing service on Windows; however, I have no idea how/if that can be accessed using PHP only.

Bonus points for simplicity! Thanks in advance.开发者_运维百科
