Just add below code in setting.json in VS Code

"phpfmt.php_bin": "C:/xampp/php/php.exe"

in my case the location is in xampp so just add your php.exe location.

On the the menu go to Preferences > Package Settings > phpfmt > Settings - User

Edit the file that will open in result of the previous action.

Specify the "php_bin" according to your php binary location,

It should contain something like this:

{
    "enable_auto_align": false,
    "indent_with_space": true,
    "passes":
    [
    ],
    "php_bin": "/Applications/MAMP/bin/php/php5.5.10/bin/php",
    "psr1": true,
    "psr2": true,
    "version": 2

}

You can use the following settings that i use for my development env, would be closest to what you are looking for.

Add the following into your settings.json in VSCode.

{
  "phpfmt.php_bin": "php",
  "phpfmt.passes": [
        "AlignPHPCode",
        "AlignTypeHint",
        "AlignDoubleArrow",
        "AddMissingParentheses",
        "ConvertOpenTagWithEcho",
        "DocBlockToComment",
        "IndentTernaryConditions",
        "JoinToImplode",
        "PSR2KeywordsLowerCase",
        "PSR2LnAfterNamespace",
        "PSR2CurlyOpenNextLine",
        "PSR2ModifierVisibilityStaticOrder",
        "PSR2SingleEmptyLineAndStripClosingTag",
        "ReindentSwitchBlocks",
        "RemoveUseLeadingSlash",
        "StripExtraCommaInArray",
        "SpaceBetweenMethods",
    ],
    "phpfmt.exclude": [
        "ReindentComments",
        "StripNewlineWithinClassBody"
    ],
    "phpfmt.psr2": false
}

First problem: Go to php.tools and click “Download ZIP” (last option in menu on the right). After download, unzip file and go to created directory in console and type:

mv fmt.phar /usr/local/bin/fmt.phar

Second problem: The atom see diffrent php vestion than system console. Run Atom, push cmd+alt+i (the chrome-like console will open) and copy into console line (at the bottom) (BTW: atom console allow you to see errors when you run plugins):

var exec = require('child_process').exec; 
var cmd = 'php -v'; 
exec(cmd, function(error, stdout, stderr) { console.log(error,stdout,stderr) });

If you will see PHP 5.5 this mean that somewhere in system you have still this version of php. Change 'php -v' to 'echo $PATH'

var exec = require('child_process').exec; 
var cmd = 'echo $PATH'; 
exec(cmd, function(error, stdout, stderr) { console.log(error,stdout,stderr) });

And you will see path that Atom see. For instance i saw:

/usr/bin:/bin:/usr/sbin:/sbin

And in /usr/bin I had wrong wersion of php. So i go there and change to right by commands (in system console):

cd /usr/bin
sudo rm php
ln -s /usr/local/Cellar/php56/5.6.15/bin/php php

After that, run Atom, go to php-fmt plugin settings and set:

Executable path (fmt): /usr/local/bin/fmt.phar

And you're done :)

First, go to File->Preferences->User settings, A window will come like below image.

Now change the setting.json file like below image and save:

If PHP is not installed in your system, download php from here: windows.php.net/download, unzip to C: drive, set "php.validate.executablePath": "C://path.to.your.php.folder//php.exe"

If php is installed in your system simply set the path of your php.exe file like below:

"php.validate.executablePath": "C://path.to.your.php.folder//php.exe"

hint: In my case I use XAMPP which is installed in the D: drive, so my setting is below

"php.validate.executablePath": "D://xampp//php//php.exe"

Mind the double forward slashes.
