I removed it, for being embarrassed about its weak key generation (!), and not wanting to enable people to unwittingly generate weak keys.  Also, someone has made a more flexible fork called PHPCoinAddress, but I would recommend at least applying my patch here, in addition to ideally studying secure key generation for your configuration/platform (at least if you are doing something high-risk/high-value in production.)  Feedback on my pull requests to PHPCoinAddress is welcome.  Thanks.
