I don't know what happened but syntax highlighting for one php file stopped to working and also icon next to the file has changed. It shows it's text file instead of PHP .

How can I fix that ?

Go to Settings|File types and ensure that this particular file name is NOT assigned to non-PHP file type, i.e. Plain Text.

Thanks this helped me out a lot when one of my files kept showing as a text file.
For some reason the entire filename was added to the Text file type. So I had "somefilename.php" as a registered pattern for Text Files. I removed it but didn't think to look there until I saw this post. Thanks!
Thanks! I had same strange behavior. I created a normal file at first by fault. Then tried to rename to *.php and it still was shown as text. Read this comment and looked under Text files. Right enough a single registered pattern was there with the full filename .php - thanks.
You sir... are a saint... this has been driving me up a wall.. For anyone wondering, just look under text files, sure enough at the end, i had like 10 files that had driven me nuts.... WOOT! YOU ROCK!
For the ones who can't find the option, go to Preferences->Editor->File Types.

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.

Whoa, my file was listed! Crazy. I wouldn't have thought to check there as I thought the extensions were wildcard patterns only in this list. Thanks - that worked for me!

Thanks to @Scotty Waggoner

For some reason the entire filename was added to the Text file type.

Find your file in Settings|FileTypes|Text|RegisteredPatterns and remove it.

Thank you for this, jesus i apparently accidentally added the full filename & type from a menu that I don't remember clicking.
Here's what you probably did, created a new file without an extension, when the window popped up asking what file type this was, you tried to add ".php" to the end of the filename at the top of the window. This doesn't rename the file though as you might think it would, rather it adds your <filename>.php to the default filetype (text) for a file with no extension. I know because, I just did it and found this thread to fix it.

Instead of trying to track down which filetype is clashing, the easiest way to fix this is to go to File > Settings on Windows (or PHPStorm > Preferences on MacOS), then search for "FILE TYPES".

Go to the troublesome filetype (in this case PHP) and look for the expected file extension (in this case .php).

enter image description here

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

enter image description here

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.

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.

That only works if you marked it as plain text before
I assume that's what he did by accident:)
Wow thank you! I had files that didn't match any defined type (icon was a text file with a cross in the corner, whatever that means) so couldn't find them. This worked!
Yes had the exact same problem as Chris, this finally fixed it for me! Thanks!

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.

Right click on the file -> Override file type -> Set as 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

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

Source of this problem

If you create a new file without adding a file extension, PHPStorm asks you if you want to auto-detect the content for syntax highlighting. It seems like this is not working for php content. If you add the extension (here .php) later, you would expect to now see the proper highlighting but because of the listing as "Auto-detect file type by content" it will switch the highlighting

Fix: Check if the not formally highlighted File is registered as wrong file type

Go to File -> Settings (Windows) or PHPStorm -> Preferences (MacOs) then search for "File Types" or navigate to Editor -> File Types

Look up "Text" and "Auto-detect file type by content" and be sure your file is not listed under "File name patterns"

Prevention: Add the .php Extension to the "File name Patterns" in the Settings

Navigate as stated in the fix above and add "*.php" under "File name patterns". If you now create a file without extension, mark it as "auto-detect" and add the extension later, it will be properly recognized as PHP-File

For me the issue was I had disable PHP inspections on the file:

enter image description here

After re-enabling "All Problems" the file appeared as it should.
