With an array, it's mission impossible. What about intuitive methods on simple value object? You'd expect such package to exist in PHP world - but there is none. So we made an object wrapper that handles all your worries:

/** @var \Symplify\ComposerJsonManipulator\ValueObject\ComposerJson $composerJson */
$composerJson = ...;

// get directories that should exists
$composerJson->getAbsoluteAutoloadDirectories();

// get minimum stability
$composerJson->getMinimumStability();

// it's ready for print
$composerJson->getJsonArray();

// change value
$composerJson->setLicense('MIT');

We've been testing the symplify/composer-json-manipulator package for a couple of weeks months, just to be sure it works well in practise.

It has over 240 000 downloads now.

3 Steps to Create ComposerJson object

1. Install the Package

composer require symplify/composer-json-manipulator --dev

Register bundle:

// config/bundles.php

declare(strict_types=1);

return [
    Symplify\ComposerJsonManipulator\ComposerJsonManipulatorBundle::class => [
        'all' => true,
    ],
];

2. Create ComposerJson with a Factory

declare(strict_types=1);

namespace App;

use Symplify\ComposerJsonManipulator\ComposerJsonFactory;
use Symplify\ComposerJsonManipulator\ValueObject\ComposerJson;
use Symplify\SmartFileSystem\SmartFileInfo;

final class SomeClass
{
    /**
     * @var ComposerJsonFactory
     */
    private $composerJsonFactory;

    public function __construct(ComposerJsonFactory $composerJsonFactory)
    {
        $this->composerJsonFactory = $composerJsonFactory;
    }

    public function createFromExisting(): ComposerJson
    {
        $fileInfo = new SmartFileInfo(getcwd() . '/composer.json');
        $composerJson = $this->composerJsonFactory->createFromFileInfo($fileInfo);

        // analyse/modify $composerJson

        return $composerJson;
    }

    public function createNew(): ComposerJson
    {
        $composerJson = $this->composerJsonFactory->createEmpty();
        $composerJson->setPreferStable(true);

        return $composerJson;
    }
}

3. Print modified ComposerJson

namespace App;

use Symplify\ComposerJsonManipulator\Printer\ComposerJsonPrinter;

class SomeClass
{
    /**
     * @var ComposerJsonPrinter
     */
    private $composerJsonPrinter;

    public function __construct(ComposerJsonPrinter $composerJsonPrinter)
    {
        $this->composerJsonPrinter = $composerJsonPrinter;
    }

    public function printAndReport(ComposerJson $composerJson)
    {
        // the file is saved + printed content returned
        $printedContent = $this->composerJsonPrinter->print(
            $composerJson,
            getcwd() . '/composer.json'
        );

        // show it to user $printedContent, so they know what was printed
    }
}

That's it! The ComposerJson is not 1:1 to full composer schema. That would be a mess full of methods and constants that are rarely used in practice. Instead, it has only the method we used.

Do you miss some method? No problem, send a pull-request to add it. That way, we'll know someone will use it and we'll be happy to merge it.

Happy coding!
