Whether a programming language is open source of closed source depends on two things - the language standards and the language implementation. As C/C++/C# are languages based on Open standards (ANSI/ISO) - so anyone can implement a compiler/toolchain for them. There are open source compilers/toolchains (like GCC, LLVM) and closed source ones (MS Visual Studio, AT&T C++, etc). Some languages like PHP, Python and Perl are open-source in terms of language design (though they might not be standardized as the part of ISO/IEEE/ANSI) and their default implementation. Many of us simply refer to them as Open source languages. In comparison, Visual Basic, ASP and similar languages are proprietary designs (done by a company) and come with a default implementation that also is proprietary - we cannot classify them as open source language/implementation.
