[Xapian-discuss] PHP documentation and examples updated

[Olly Betts]

Sorry it's taken me a while to sort out, but here's the latest
documentation in SVN:

http://svn.xapian.org/trunk/xapian-bindings/php/docs/bindings.html?view=co

The examples are now split into ".php4" and ".php5" versions.

And I've implemented a version of "simpleexpand" in PHP too.  This
demonstrates the use of relevance feedback.

Cheers,
    Olly
