Phpstorm File type errors

The article.php file does not display the same type as other PHP files
The code has no color, and no hint is entered

The code also can't run without the option of run, I think there is a problem with his file type

The file created by the time you created, forgot to add the suffix name, the results pop-up window let me choose the type, I direct point of OK

And then change the name of article into article.php.
Then delete the source file to create the article.php file again or this. There is no way to solve,
I am using the PHPSTORM10 mac English version, hope to tell how to solve this problem.
This is the edit option.

This is all the options

Option inside Editor = File types Find text, delete the article you added (minus)

Why tangle, delete, re-build a chant
