Koded Standard Library

A standard library for shareable classes and functions.

Classes

Immutable

• get(string $index, $default = null)
• has($index): bool
• equals(string $propertyA, string $propertyB): bool
• find(string $index, $default = null)
• extract(array $keys): array
• filter(iterable $data, string $prefix, bool $lowercase = true, bool $trim = true): array
• namespace(string $prefix, bool $lowercase = true, bool $trim = true)
• count()
• toArray(): array
• toJSON(int $options = 0): string
• toXML(string $root): string
• toArguments(): Arguments

Arguments

(implements Immutable methods)

• set(string $index, $value)
• import(array $values)
• upsert(string $index, $value)
• bind(string $index, &$variable)
• pull(string $index, $default = null)
• delete(string $index)
• clear()
• toImmutable(): Immutable

ExtendedArguments

ExtendedArguments extends Arguments

• flatten(): ExtendedArguments

Supports dot-notation for index names. Example:

$args = new \Koded\Stdlib\ExtendedArguments([
    'foo' => [
        'bar' => [
            'baz' => 42
        ]
    ]
]);

$args->get('foo.bar');
// returns ['baz' => 42]

$args->get('foo.bar.baz');
// returns 42

$args->flatten();
// returns ['foo.bar.baz' => 42]

$args->set('foo.bar', 'baz');
// ['foo' => ['bar' => 'baz']]

Config

Class Config works as a parameter bag that provides ways to fill it from files or other Config instances. There are 2 common patterns to populate the config,

either you can fill the Config instance from config files:

$app->config()->fromPhpFile('myconfig.php');
$app->config()->fromJsonFile('myconfig.json');
$app->config()->fromEnvFile('.env');
$app->config()->fromIniFile('myconfig.ini');

or alternatively you can define the configuration options in the instance that calls fromObject,

$app->config()->fromObject(MyConfig::class);
$app->config()->fromObject($myconfig); // $myconfig is instance of Config

Other interesting way to load configuration is from an environment variable that points to a file

$app->config()->fromEnvVariable('MY_APP_SETTINGS');

In this case, before launching the application you have to set the env variable to the file you want to use. On Linux and OSX use the export statement

export MY_APP_SETTINGS='/path/to/config/file.php'

or somewhere in your app bootstrap phase before constructing the Api instance

putenv('MY_APP_SETTINGS=/path/to/config/file.php');

• fromEnvironment( array $variableNames, string $namespace = '', bool $lowercase = true, bool $trim = true ): Configuration
• fromJsonFile(string $file): Configuration
• fromPhpFile(string $file): Configuration
• fromEnvVariable(string $variable): Configuration
• fromIniFile(string $file): Configuration
• fromObject($object): Configuration
• withParameters(array $parameters): Configuration
• silent(bool $silent): Configuration
• build(string $context): Configuration

Mime

• type(string $extension, int $index = 0): string
• types(string $extension): array
• supports(string $type): bool
• extensions(string $type): array

UUID

Class UUID generates Universally Unique Identifiers following the RFC 4122.

• v1($address = null): string
• v3(string $namespace, $name): string
• v4(): string
• v5(string $namespace, string $name): string
• valid(string $uuid): bool
• matches(string $uuid, int $version = 4): bool
• toBase64(string $uuid): string
• fromBase64(string $base64): string

ULID

Class ULID generates Universally Unique Lexicographically Sortable Identifiers

• generate(int $count = 1): self
• fromULID(string $ulid): self
• fromUUID(string $ulid): self
• fromTimestamp(float $timestamp): self
• fromDateTime(string $datetime): self
• toULID(): array|string
• toUUID(): array|string
• toDateTime(): array|DateTime
• count(): int
• valid(string $uuid): bool

Functions

function arguments(...$values): Argument;
function extended(...$values): ExtendedArguments;
function value(...$values): Data;
function tap(mixed $value, callable $callable = null): mixed;
function camel_to_snake_case(string $string): string;
function env(string $name = null, mixed $default = null, array $initialState = null): mixed;
function error_log(string $function, string $message, $data): void;
function htmlencode(string $input, string $encoding = 'UTF-8'): string;
function is_associative(array $array): bool;
function json_serialize($value, int $options = JSON_PRESERVE_ZERO_FRACTION | JSON_UNESCAPED_SLASHES): string;
function json_unserialize(string $json, bool $associative = false);
function now(): DateTimeImmutable;
function randomstring(int $length = 16, string $prefix = '', string $suffix = ''): string;
function rmdir(string $dirname): bool;
function snake_to_camel_case(string $string): string;
function to_delimited_string(string $string, int $delimiter): string;
function to_kebab_string(string $string): string;
function xml_serialize(string $root, iterable $data): string;
function xml_unserialize(string $xml): array;
