A company has an application that was built in ASP/SQL Server which runs on a Windows platform. A new module is being planned. A new programmer is going to build this module (ie. not the programmer who built the original system.)
The new programmer suggests writing the new code in PHP (instead of ASP). The new programmer prefers open source languages and suggests that the company should keep in mind that with the introduction of ASP.Net you never know if Microsoft will stop supporting ASP down the road.
The question is: is it a good idea to develop the new module in PHP, or should it be written ASP, like the rest of the application. The company is conerned about 2 things: (1) how would a PHP module perform in the Windows environment? and (2) would it become an issue in the future regarding maintaining the system ie. having modules built in different languages?
Though this info is general, any input from anybody who develops web applications and has experience in this area would be appreciated.
Presently, the company is not certain if the module should be developed in PHP or ASP.
