Php Solutions
Solution 1 - Php
Go to Settings|File types and ensure that this particular file name is NOT assigned to non-PHP file type, i.e. Plain Text.
Solution 2 - Php
In PHPStorm 10 you have to go to File->Settings and once there Editor->File Type. If plain text probably you will find it on the file type "Text". Check under "registeded patterns" and delete your file from there.

> For some reason the entire filename was added to the Text file type.
Find your file in Settings|FileTypes|Text|RegisteredPatterns and remove it.
Solution 4 - Php
The easiest way to fix this is to go to File > Settings on Windows (or PHPStorm > Preferences on MacOS), then search for "FILE TYPES".
Scroll down to the troublesome filetype (in this case PHP).
Then look for the expected file extension (in this case .php).
If you see it's missing (as above), then just add it by pressing the + button under "Registered Patterns". Then in the "Add Wildcard" window that opens you would type: *.php
PHPStorm will then tell you that it's mapped to another filetype (the one that's caused this problem), and would you like to move it to this one instead. Simply click "Yes" and it will fix everything. You're all done!
This is much easier than hunting around the other file types for broken one to delete.
Solution 5 - Php
I'm not sure if this function is restricted only to phpStorm 9, but there's a simpler solution: if the extension of a file is .php, you can right click on the file in project browsing menu and click "mark as php". That fixed the problem for me.
Solution 6 - Php
In PHPStorm 2019.1 on MacOS:
PhpStorm > Preferences > Editor > File Types > Recognized File Types > Text
Remove the entry from Registered Patterns which contains your file-name, i.e remove File.php if File.php is the problematic file.
Solution 7 - Php
Same problem but my file wasn't in "Text" but "File type auto-detected by file content"
> PhpStorm > Preferences > Editor > File Types > Recognized File Types > > File type auto-detected by file content
Solution 8 - Php
This question is old but I answer for someone that couldn't solve this:
You may have removed one of the PHP start(<?php) or end (?>) tags and is therefore displayed in plain text
Solution 9 - Php
Right click on the file -> Override file type -> Set as PHP
