WinBinder is an open source extension to PHP, the script programming language. It allows PHP programmers to easily build native Windows applications, producing quick and rewarding results with minimum effort. Even short scripts with a few dozen lines can generate a useful program, thanks to the power and flexibility of PHP.
PHP is a very popular scripting language that is used mostly for web development but is gaining popularity as a general-purpose scripting language.
WinBinder itself is comprised of a DLL (which is the actual PHP extension), a small set of PHP scripts and some auxiliary files. Of course a minimal PHP installation is required as well.
