SmartEmailing \ Types

Missing data types for PHP 7.1. Highly extendable.

Neverending data validation can be tiresome. Either you have to validate your data over and over again in every function you use it, or you have to rely it has already been validated somewhere else and risk potential errors. Smelly, right?

Replacing validation hell with Types will make your code much more readable and less vulnerable to bugs.

Types wrap your data in value objects that are guaranteed to be valid and normalized; or not to exist at all. It allows you to use specific type hints instead of primitive types or arrays. Your code will be unbreakable and your IDE will love it.

Installation

The recommended way to install is via Composer:

composer require smartemailing/types

How does it work

It is easy. You just initialize desired value object by simple one-liner. From this point, you have sanitized, normalized and valid data; or SmartEmailing\Types\InvalidTypeException to handle.

Types consist from:

String-extractable types - validated strings (E-mail address, Domains, Hexadecimal strings, ...)
Int-extractable types - validated integers (Port)
Float-extractable types - validated floats (SigmoidValue, Part, ...)
Enum-extractable types - enumerables (CountryCode, CurrencyCode, GDPR's Lawful purpose, ...)
Composite (Array-extractable) types - structures containing multiple another types (Address, ...)
DateTimes - extraction of DateTime and DateTimeImmutable
Primitive types extractors and unique arrays

Different types provide different methods related to them, but all types share this extraction API:

Wrapping raw value

<?php

declare(strict_types = 1);

use SmartEmailing\Types\Emailaddress;
use SmartEmailing\Types\InvalidTypeException;

// Valid input

$emailaddress = Emailaddress::from('[email protected]'); // returns Emailaddress object
$emailaddress = Emailaddress::from($emailaddress); // returns original $emailaddress

// Invalid input

$emailaddress = Emailaddress::from('bla bla'); // throws InvalidTypeException
$emailaddress = Emailaddress::from(1); // throws InvalidTypeException
$emailaddress = Emailaddress::from(false); // throws InvalidTypeException
$emailaddress = Emailaddress::from(null); // throws InvalidTypeException
$emailaddress = Emailaddress::from([]); // throws InvalidTypeException
$emailaddress = Emailaddress::from(new \StdClass()); // throws InvalidTypeException

// Nullables

$emailaddress = Emailaddress::fromOrNull(null); // returns NULL
$emailaddress = Emailaddress::fromOrNull('bla bla'); // throws InvalidTypeException
$emailaddress = Emailaddress::fromOrNull('bla bla', true); // returns null instead of throwing

Extraction from array

This is really useful for strict-typing (validation) multidimensional arrays like API requests, forms or database data.

<?php

use SmartEmailing\Types\Emailaddress;
use SmartEmailing\Types\InvalidTypeException;

$input = [
	'emailaddress' => '[email protected]',
	'already_types_emailaddress' => Emailaddress::from('[email protected]'),
	'invalid_data' => 'bla bla',
];

// Valid input

$emailaddress = Emailaddress::extract($input, 'emailaddress'); // returns Emailaddress object
$emailaddress = Emailaddress::extract($input, 'already_types_emailaddress'); // returns original Emailaddress object

// Invalid input

$emailaddress = Emailaddress::extract($input, 'invalid_data'); // throws InvalidTypeException
$emailaddress = Emailaddress::extract($input, 'not_existing_key'); // throws InvalidTypeException

// Nullables 

$emailaddress = Emailaddress::extractOrNull($input, 'not_existing_key'); // returns null
$emailaddress = Emailaddress::extractOrNull($input, 'invalid_data'); //  throws InvalidTypeException
$emailaddress = Emailaddress::extractOrNull($input, 'invalid_data', true); // returns null instead of throwing

// Default values
$emailaddress 
	= Emailaddress::extractOrNull($input, 'not_existing_key') 
	?? Emailaddress::from('[email protected]'); 
	// uses null coalescing operator to assign default value if key not present or null

$emailaddress 
	= Emailaddress::extractOrNull($input, 'not_existing_key', true) 
	?? Emailaddress::from('[email protected]'); 
	// uses null coalescing operator to assign default value if key not present or null or invalid

String-extractable types

They can be easily converted back to string by string-type casting or calling $type->getValue().

Array-types

Types provide another kind of Array-extractable types: Unique primitive-type arrays. Their purpose is to hold unique set of primitives. They implement \Countable and \IteratorAggregate and natively support set operations.

All Array-types share following features:

static empty() : self Creates new empty instance of desired array-type.
split(int $chunkSize): self[] Splits current instance into array of several instances, each with maximum data-set size of $chunkSize.
merge(self $toBeMerged): self Returns new instance with data-set combined from parent and $toBeMerged instances. Both source instances stay unchanged.
deduct(self $toBeDeducted): self Returns new instance with data-set containing all items from parent that are not contained in $toBeDeducted. Both source instances stay unchanged.
count(): int Returns data-set size.
isEmpty(): bool Returns true if data-set is empty, false otherwise.

Array-types-specific extractors:

static extractOrEmpty(array $data, string $key): self Behaves like standard ::extract() method, but returns empty set when $data[$key] is null or not set.
static extractNotEmpty(array $data, string $key): self Behaves like standard ::extract() method, but throws InvalidTypeException when $data[$key] is not set, null or empty array.

UniqueIntArray

SmartEmailing\Types\UniqueIntArray

UniqueIntArray is able to hold unique set of integers.

Can be created from:

// duplicate values will be discarted
// keys are ignored

UniqueIntArray::from(
	[
		1, 2, 2, 3, 3, 3, 4 
	]
);

Type-specific methods:

getValues(): int[] Returns data-set of unique integers as array.
toArray(): int[] Is just alias for getValues().
add(int $id): bool Adds another integer to the data-set. Returns false if integer has already been there.
remove(int $id): void Removes integer from the data-set, if present.
contains(int $id): bool Returns true if $id is contained in the data-set, false otherwise.

UniqueStringArray

SmartEmailing\Types\UniqueIntArray

UniqueStringArray is able to hold unique set of strings.

Can be created from:

// duplicate values will be discarted
// keys are ignored

UniqueStringArray::from(
	[
		'a', 
		'b', 
		'c', 
		'all work and no play makes jack a dull boy',
		'all work and no play makes jack a dull boy',
		'all work and no play makes jack a dull boy',
	]
);

Type-specific methods:

getValues(): string[] Returns data-set of unique strings as array.
toArray(): string[] Is just alias for getValues().
add(string $id): bool Adds another string to the data-set. Returns false if string has already been there.
remove(string $id): void Removes string from the data-set, if present.
contains(string $id): bool Returns true if $id is contained in the set, false otherwise.

Enum-extractable types

Enum-extractable types are types that can contain single value from defined set. They are based on kkk

All Enum-extractable types share following features:

getValue() : string Returns enum-value
equals(self $enum): bool Returns true if $enum contains same value as parent.
equalsValue(string $value): self Returns true if parent contains the same value as $value.

Enums can be created using standard extractors or using their constants:

CurrencyCode::from(
	CurrencyCode::EUR
);
CurrencyCode::from(
	'EUR'
);
