read PHP file in SD card

Hi guys,
Is it possibile to open a php page from arduino yun?
The file php was located on the SD card in the right directory (/arduino/www), and i can view the file from a browser, but when I try to open it, I can't view the page, and the php file downloads.

I've already installed php5 and php5-cgi on the arduino.

Please help me!
