[Serializer] Add SnakeCaseToCamelCaseNameConverter

[thibaut22200]

Document symfony/symfony#58060
and closes #20151

The example here seems to be the same as the one for the CamelCaseToSnakeCaseNameConverter. That doesn't look right to me.

@xabbuh Fixed the example, thanks you.

I think there is still some misunderstanding. When the name converter is being used the name of the property is converted but not the value. So I would expect a class with a property like $full_name and a key like fullName in the normalised data.

Suggested change

	class Person
	{
	public function __construct(
	private string $fullName,
	) {
	}
	public function getFullName(): string
	{
	return $this->fullName;
	}
	}
	$john = new Person('john_doe');
	$normalizer->normalize($john);
	// ['full_name' => 'johnDoe'];
	$john = $normalizer->denormalize(['full_name' => 'johnDoe'], 'Person');
	// Person object with fullName: 'jonh_doe'
	class Person
	{
	public function __construct(
	private string $full_name,
	) {
	}
	public function getFullName(): string
	{
	return $this->full_name;
	}
	}
	$john = new Person('john');
	$normalizer->normalize($john);
	// ['fullName' => 'john'];
	$john = $normalizer->denormalize(['fullName' => 'john'], 'Person');
	// $john->getFullName() -> 'john'

I am not sure if it works this way when the property is not public and the getter has a camel case name.

[dunglas]

Indeed, it's for camel_cased public properties and getters/setters (Eloquent-like).

Hi!

We've rewritten the Serializer documentation. In this process, we've merged the contents of the component and framework documentation. Do you have time to update this PR to instead document this new feature in https://symfony.com/doc/current/serializer.html#camelcase-to-snake-case ? No worries if you can't make the change, we can always take over this PR and make this change.
