\Noname\Arr

A helper library for working with arrays.

Arr Methods

static flatten(array $array, string $separator = '.') : array

Flatten an associative array using a custom separator. This method will use a dot (.) for $separator by defult.

static dot(array $array) : array

Alias for Arr::flatten() that always uses a dot (.) separator.

static each(array $array, callable $callable) : array

Recursively assign the callable's return value to each array item. Array keys are preserved.

\Noname\Collection

Create a Collection with an associative array to provide helpful methods for working with your data.

Collection implements the following interfaces: Countable, ArrayAccess, IteratorAggregate, Serializable, JsonSerializable

Usage Example

Collection Methods

__construct(array $items = []) : Collection

Creates an instance of Collection. Optionally pass an associative array for $items to prefill the collection with items.

static make(...$arrays) : Collection

Make a collection from one or more arrays.

set(string $key, mixed $value) : void

Add an item to the collection. If $key already exists in the collection it will be overwritten.

get(string|array $key, mixed $default = null) : mixed

Get an item from the collection. Returns $default if item not found.

Passing an array of item keys for the value of $key will result in multiple items being returned as an array. Keys that are missing from the collection will be returned with a value of $default.

has(string $key) : bool

Check if the collection has an item with same $key.

is(string $key, mixed $value, mixed $operater = null) : bool

Compare an item's value against $value. By default, the method will check if the item's value is equal to $value. Optionally, you may supply an $operator to change the comparison logic.

Supported $operator values: =, ==, ===, >, >=, <, <=, <>, !=

Note: = and == are the same, but === is will perform a strict comparison. <> and != are the same.

pluck(string $key, mixed $default = null) : mixed

Pluck an item from the collection. If $key doesn't exist in the collection then $default will be returned.

delete(string $key) : void

Remove an item from the collection.

destroy() : void

Remove all items from the collection.

count() : int

Returns the count of all of the items in the collection.

keys() : array

Returns an array containing the keys of all of the items in the collection.

values() : array

Returns an array containing the values of all of the items in the collection.

all() : array

Alias for toArray().

toArray() : array

Returns an array of all of the items in the collection.

toJson() : string

Returns collection as JSON.

flatten() : array

Flatten all of the items in the collection using dot (.) notation.

\Noname\Str

A helper library for working with strings.

Str Methods

static startsWith(string $string, string $prefix, bool $caseSensitive = true) : bool

Checks if string starts with given prefix. By default this method is case-sensitive.

static endsWith(string $string, string $suffix, bool $caseSensitive = true) : bool

Checks if string ends with given prefix. By default this method is case-sensitive.

static equals(string $a, string $b, bool $caseSensitive = true) : bool

Checks if two strings equal each other. By default this method is case-sensitive.

static contains(string $string, string $search, bool $caseSensitive = true) : bool

Checks if string contains another string. By default this method is case-sensitive.

static toArray(string $string) : array

Splits a string into an array containing each character.

\Noname\Validator

Use Validator to validate your data based on a set of rules.

Usage Example

Built-in Validation Types

• *, any Always pass validation for any data type
• null Validate that value is null
• bool, boolean Validate that value is boolean
• scalar Validate that value is scalar (integer, float, string or boolean)
• str, string Validate that value is string
• num, numeric Validate that value is numeric
• int, integer Validate that value is integer
• float, double Validate that value is float/double
• alnum, alphanumeric Validate that value only contains alpha-numeric characters
• alpha Validate that value only contains alpha characters
• arr, array Validate that value is array
• object Validate that value is object
• callable Validate that value is callable
• email Validate that value is a valid email address
• ip Validate that value is either of IPv4 or IPv6
• ipv4 Validate that value is IPv4
• ipv6 Validate that value is IPv6
• date, datetime Validate that value is date/datetime
• resource Validate that value is a resource
• stream Validate that value is a stream
• dir, directory Validate that value is a directory
• file Validate that value is a file

Hint: Adding [] to any type (e.g. int[]) will validate an array of values.

Validator Methods

__construct(array $values, array $rules) : Validator

Create an instance of Validator.

addType(string $typeName, array $typeRule) : void

Add a custom validator type. The following example will add a type of equals_2 which validates that the value is equal to 2 and will set an error otherwise.

Note: Custom types must be added prior to calling validate() or an InvalidArgumentException will be thrown.

addValue(string $name, mixed $value) : void

Add value to dataset that is to be validated.

addValues(array $values) : void

Add multiple values to dataset that is to be validated.

values() : array

Returns an array of the values that are set to be validated.

addRule(string $name, mixed $rule) : void

Add a rule to the validator.

addRules(array $rules) : void

Add multiple rules to the validator.

rules() : array

Returns an array of the rules that are set for validation.

validate() : bool

Validate the set data based on the set rules.

hasErrors() : bool

Checks if any errors were set during validation.

getErrors() : array

Returns an array of the errors that were set during validation.

static is(string $type, mixed $value) : bool

Static method to check if $value is valid $type. You can pass any of the built-in validator types for $type.

This method is useful when validating a single value.

static is{Type}(mixed $value) : bool

Similar to is(), except type is passed in the method name.

Note: These methods are case-sensitive. If you are having issues it is recommended that you use is() instead.
