I have released the source code of my project "PC/SC for PHP" today.
It is an extension for PHP using pcsc-lite for smart card communication based on the PC/SC standard.
It is just an attempt to realize the idea of native and server side smart card communication within a PHP project. It could for example be useful if your web application needs access to crypto for signing, encryption etc. using a smart card as a SAM (Secure Application Module) or as a HSM (Hardware Security Module).
Have fun and please send me some comments...!
