The developer of VoltDB is here. Ning Shi just finished a very good PHP extension, which is a big improvement in the performance and usability of the old PHP extension.
The old extension was a SWIG cover around the C ++ client library, which was verbose due to weaker VAR support and C ++ reflex. The server also did not support binding parameters as strings for you, which meant that the client had to know the signature of the procedure in front, and the application had to provide it.
The new extension does not have PHP code, so it loads faster and has a more idiomatic PHP interface that uses PHP arrays and does not require you to declare a procedure and its parameters before calling it.
The new client is on the page.
