Php code formatter / beautifier and php beautification in general

PHP Code Beautifier is a useful free tool that should do what you're after, although their download page does require an account to be created.

The tool has been declined into 3 versions:

A GUI version which allow to process file visually.

A command line version which allow to be batched or integrated with other tools (CVS, SubVersion, IDE ...).

As an integrated tool of PHPEdit.

Basically, it'll turn:

if($code == BAD){$action = REWRITE;}else{$action = KEEP;}
for($i=0; $i<10;$i++){while($j>0){$j++;doCall($i+$j);if($k){$k/=10;}}}

into

if ($code == BAD) {
    $action = REWRITE;
} else {
    $action = KEEP;
}
for($i = 0; $i < 10;$i++) {
    while ($j > 0) {
        $j++;
        doCall($i + $j);
        if ($k) {
            $k /= 10;
        }
    }
}

Format code command for PHP/HTML in Visual Studio Code

Update 2021-07-21

It's been more than half a decade since I first wrote this answer. The extensions to which I originally linked are abandoned, and Visual Studio Code's intrinsic PHP support hasn't improved, which is disappointing. The only decent extension still standing of which I'm aware is PHP Intelephense, which uses a freemium model: basic features are free, and a lifetime license is $12 USD as of writing.

The free version of Intelephense supports code formatting with the usual shortcuts (Alt + Shift + F on Windows and Linux, ⌥⇧F on macOS). Visual Studio Code continues to lack built-in support for PHP code formatting and will direct you to the extension marketplace if you attempt to format PHP without an appropriate extension installed.

Original answer

Visual Studio Code has pretty awesome PHP support. What it lacks is covered by extensions. A quick search reveals at least three (1, 2, and 3) that claim to support PHP formatting.

They mostly seem to use the standard shortcut of Alt + Shift + F on Windows/Linux, with varying shortcuts on Mac. If you're on Mac, give ⌥⇧F a try.

Beautify HTML stored in a string on PHP

Using DomDocument we load the html passing the LIBXML_HTML_NOIMPLIED flag

which will prevent the loadHTML method to add the extra html wrapper.

We save as XML to get the nice indentation, while passing the $dom->documentElement parameter to prevent the XML header.

$html = '<body><div><p>hello</p><div></body>';

$dom = new DOMDocument();

$dom->preserveWhiteSpace = false;
$dom->loadHTML($html,LIBXML_HTML_NOIMPLIED);
$dom->formatOutput = true;

print $dom->saveXML($dom->documentElement);

This will output

<body>
  <div>
    <p>hello</p>
    <div/>
  </div>
</body>

Notice that the HTML was fixed for you as the second div should have been a closing tag, I assume.

If we pass the proper HTML as the input string, the output will be as you require

$html = '<body><div><p>hello</p></div></body>';

<body>
  <div>
    <p>hello</p>
  </div>
</body>

PHP HTML Formatter Beautifier

VSCode Prettier not formatting PHP

Core prettier does not support PHP¹, and thus neither does the plugin for VSCode/VSCodium.
Luckily the designers of prettier seems to have thought of this and implemented a plugin system².

According to the prettier-vscode repo, all you need to do to use a plugin is to add it and prettier to your package.json³

So for php support your package.json would need to contain:

{
  "devDependencies": {
    "@prettier/plugin-php": "0.14.3",
    "prettier": "2.0.5"
  }
}

How can I format PHP files with HTML markup in Visual Studio Code?

The extension Beautify (from HookyQR) just does it very well. Either add PHP, and any other file extension type, to the configuration. As said by Nico, here is an example:

Go to user settings (Ctrl + Shift + P → User settings (UI) or Ctrl + , (comma)
Search for Beautify in the field above. And click on "Edit in settings.json" for "Beautify: Config".
For the "html" section, add "php" and "blade".

###Usage

You can invoke it directly. Press F1, and then write Beautify. The auto completion gives you two choices, "Beautify file" and "Beautify selection". Choose the one you need, and it will do the job. That's a straightforward direct way.

Sample Image

You can also add a keybinding to have a keyboard shortcut. Here is how to do it:

Open keybindings.json (go to menu File → Preferences → Keyboard Shortcuts)
Click in the above. Open and edit file keybindings.json
Add the following into the closed brackets, []
```
{
       "key": "alt+b",
       "command": "HookyQR.beautify",
       "when": "editorFocus"
}
```
Choose any key you want, and make sure you don't override an existing one. Search first in the left side if it exists or not.

Note that all of those things are well documented in the description of the extension.

Extra: Note about blade

(suite to @Peter Mortensen clarification pinpoint)

blade or blade.php

If you are confused if it's blade or blade.php for the setting! I'll clear it up for you! It's blade! That's vscode keyword for the language!

How do you know ?

First if you open the list of languages as by the image bellow:

Sample Image

Write blade

Sample Image

You can see Laravel Blade (blade)! The language keyword is in the paratheses! blade!

Well but how to check!

Try with blade.php in the settings!

Sample Image

Try to beautify

Sample Image

You'll get an asking context menu for what language (html, css, js)!

Sample Image

So it doesn't works!

To really know ! Put back blade!
And it will work and beautify directly!

How well it works with blade

The awesome answer to that! Is try it, and see for yourself!

But if you ask me! I'll say it does work as with html! It can be too handy! And you may need to fix some lines! Depending on your expectations and your style!

Here an illustration! I screwed the indentation in purpose

Sample Image

And here the beautification result:

Is it possible to auto format PHP in Sublime Text 2?

I've been searching this before also, but with no avail. Sublime text 2 probably doesn't support formatting PHP code natively. I have looked into ST2 packages - http://wbond.net/sublime_packages/community, but there is also nothing. Probably you'll have to do this in another editor.

Of course it would be nice, if someone would write a package for this, 'cause packages for formatting JS, JSON, HTML.. already exist.
