Android emulator does not recognize .php extension for web pages

I am trying to write a php code for mobile web app. But the problem 开发者_JS百科is when I test that page in android emulator then it says error loading. when I turn it back to .html then it loads that page.

Can someone tell me why and how to solve this?

Try your page on web browser before the emulator. Seems it's not a emulator issue.
