Installation

You can install the package via composer:

Usage

firstIf

Returns the first element of an array if a condition is met.

$array = [1, 2, 3];
$result = Arr::firstIf($array, true); // Returns 1

lastIf

Returns the last element of an array if a condition is met.

<?php
$array = [1, 2, 3];
$result = Arr::lastIf($array, true); // Returns 3

chunk

<?php
$array = [1, 2, 3, 4, 5, 6];
$result = Arr::chunk($array, 2, fn($chunk) => array_sum($chunk)); // Returns [3, 7, 11]

getAnyValues

<?php
$array = ['a' => 1, 'b' => 2, 'c' => 3];
$result = Arr::getAnyValues($array, ['b', 'c']); // Returns 2

hasAnyValues

Checks if any of the specified values exist in an array.

<?php
$array = ['a' => 1, 'b' => 2, 'c' => 3];
$result = Arr::hasAnyValues($array, [2, 4]); // Returns true

hasAllValues

Checks if all specified values exist in an array.

<?php
$array = ['a' => 1, 'b' => 2, 'c' => 3];
$result = Arr::hasAllValues($array, [1, 2]); // Returns true

ifOk

Returns the array if a condition is met, otherwise returns null.

<?php
$array = [1, 2, 3];
$result = Arr::ifOk($array, true); // Returns [1, 2, 3]

missing

Returns a list of keys that are missing from an array.

<?php
$array = ['a' => 1, 'b' => 2];

isMissing

Checks if a key is missing from an array.

<?php
$array = ['a' => 1, 'b' => 2];
$result = Arr::isMissing($array, 'c'); // Returns true

range
