    wxPHP

    wxPHP

    PHP bindings for the cross-platform GUI library wxWidgets.

    wxPHP is a php binding/wrapper for the cross-platform library wxWidgets, which gives you the ability to develop desktop applications using the php programming language. This applications can be executed on windows, linux and macosx using the same code base with a native look and feel. One of the ideas is that you can use your php web applications code base and logic to create native desktop applications that communicate to them transparently. This way you can give your users a seamless and native experience from the desktop while staying in sync with your web apps. There are many more use cases, but we invite you to download and try this project by your self. We hope everyone can enjoy it as much as we have enjoyed developing it.
