Usage

Json

The Starburst\Utils\Json class provides static methods for encoding and decoding Json in PHP. Below, you'll find detailed documentation on how to use it:

encode(mixed $value): string

This method accepts a variable of any type and converts it to a JSON string.

Parameters:

• $value (mixed): The value you want to encode to JSON.

Returns:

• JSON Encoded string

Usage:

$jsonString = \Starburst\Utils\Json::encode(["name" => "John Doe", "age" => 30]);

decode(string $value): mixed

This method accepts a JSON string and decodes it to the corresponding PHP value or array.

Parameters:

• $value (string): The JSON string you want to decode.

Returns:

• The PHP value that was encoded in the JSON string. If json is an object it's returned as an assoc array

Usage:

$phpValue = \Starburst\Utils\Json::decode($jsonString);

decodeArray(string $value): array

This method decodes a JSON string to an associative array in PHP.

The method throws a JsonException if the decoded value is not an array.

Parameters:

• $value (string): The JSON string you want to decode to an array.

Returns:

• The associative array that was encoded in the JSON string.

Usage:

$associativeArray = \Starburst\Utils\Json::decodeArray($jsonString);

decodeList(string $value): array

This method decodes a JSON string to a numeric array (list) in PHP.

The method throws a JsonException if the decoded value is not a list.

Parameters:

• $value (string): The JSON string you want to decode to an array.

Returns:

• The numeric array (list) that was encoded in the JSON string.

Usage:

$list = \Starburst\Utils\Json::decodeList($jsonString);

Validators

The Starburst\Utils\Validators class provides static methods to validate different types of input.

isUnicode(mixed $value): bool

This function checks if the provided value is a valid UTF-8 string.

Parameters:

• $value (mixed): The value you want to check.

Returns:

• True or false. It will always return false for none string types

Usage:

$isValid = \Starburst\Utils\Validators::isUnicode($value);

isKennitala(mixed $value): bool

This function checks if the provided value is a valid kennitala.

Parameters:

• $value (mixed): The value you want to check.

Returns:

• True or false

Usage:

$isValid = \Starburst\Utils\Validators::isKennitala($value);

isEmail(string $value): bool

This function checks if the provided string is a valid email address. Note that it only checks the syntax of the email and not if the email domain actually exists.

Parameters:

• $value (string): The value you want to check.

Returns:

• True or false

Usage:

$isValid = \Starburst\Utils\Validators::isEmail($value);

GetArrayCopy

Trait that helps convert an object into an assoc array.

It supports value resolvers that can be used to format some properties in a custom way.

Example

class TestObject
{
	use \Starburst\Utils\Traits\GetArrayCopyTrait;
	
	public function __construct(
		public int $id,
		#[\Starburst\Utils\Attributes\DateFormat('Y-m-d')]
		public \DateTimeImmutable $startDate,
		public \DateTimeImmutable $createdOn,
		#[\Starburst\Utils\Attributes\HiddenProperty]
		public string $internalField,
		#[\Starburst\Utils\Attributes\CustomName('parent')]
		public ?TestObject $parentObject = null,
	) {}
}

$obj = new TestObject(
	1,
	new DateTimeImmutable('2024-05-24 08:00:00'),
	new DateTimeImmutable('2024-05-20 12:23:01'),
	'internalValue'
);

$obj->getArrayCopy() === [
	'id' => 1,
	'startOn' => '2024-05-24',
	'createdOn' => '2024-05-20 12:23:01',
	'parent' => null,
];

Configure custom value resolvers

#[\Attribute(\Attribute::TARGET_PROPERTY)]
class CustomAttribute {}
class CustomResolver implements \Starburst\Utils\ValueResolvers\ValueResolver
{
	/**
	 * @param \WeakMap<object, mixed> $tracker
	 */
	public function resolve(mixed $value, \WeakMap $tracker, ?\ReflectionProperty $reflectionProperty = null): mixed
	{
		$attrs = $reflectionProperty?->getAttributes(CustomAttribute::class);
		if (!$attrs) {
			return $value;
		}
		if ($value instanceof \DateTimeInterface) {
			return $value->format('j.m k\l. H:i');
		}
		
		return 'Random string';
	}

}

$collection = new \Starburst\Utils\ValueResolvers\ResolverCollection(
	new \Starburst\Utils\Tests\Stubs\CustomValueResolver(),
);

$obj = new class (1) {
	use \Starburst\Utils\Traits\GetArrayCopyTrait;
	
	public function __construct(
		#[CustomAttribute]
		private mixed $value,
	) {}
};

$obj->getArrayCopy() === [
	'value' => 'Random string'
];

$obj = new class (new \DateTimeImmutable('2024-05-24 08:12:42')) {
	use \Starburst\Utils\Traits\GetArrayCopyTrait;
	
	public function __construct(
		#[CustomAttribute]
		private mixed $value,
	) {}
};

$obj->getArrayCopy() === [
	'value' => '24.05 kl. 08:12:42'
];
