It looks neat. I'm sorry I don't have much feedback, but I think this line is incorrect in your readme.

file_put_contents( "key.txt", $k->Export() );

I think you meant $key->Export(). Just a heads up to save the copy and pasters.

Ack. You are absolutely right, that was my own copy/paste issue. Fixed now, thanks!
