These helpers, among other things, provide a **significantly improved** (about **10-30 times faster**) analogues of built-in PHP array functions, like `unique()` or `intersect()`. ### `unique()` function [](#unique-function) This is an improved (**30 times faster!**) implementation of standard `array_unique()` PHP function. ``` $arr = [1,2,3,1,2,3]; $unique = \Mufuphlex\Util\ArrayUtil::unique($arr); // [1,2,3] ``` ### `intersect()` function [](#intersect-function) This is an improved (**10 times faster!**) implementation of standard `array_intersect()` PHP function. ``` $a = [1,2,3]; $b = [2,3,4]; $c = [3,4,5]; $result = \Mufuphlex\Util\ArrayUtil::intersect($a, $b, $c); // [3] ``` ### `cutBy*()` functions [](#cutby-functions) If you need to remove particular elements from an array by elements' keys, `cutByWhitelist(array $array, array $map)` and `cutByBlacklist(array $array, array $map)` can be very useful. `cutByWhitelist()` **leaves** in `$array` only elements which are listed in the `$map` and `cutByBlacklist()` - just in opposite - **removes** from `$array` elements listed in `$map`. Moreover, these functions can not only remove, but also modify `$array`'s members via callbacks - smth like an extended version of standard PHP function `array_walk()`. **How to use it?** Let's consider the following sample array: ``` $array = [ 'result' => [ 'one' => [ 'param 1' => 1, 'param 2' => 2, 'param 3' => 3, ], 'another' => [ 'param 1' => 4, 'param 2' => 5, 'param 3' => 6, ], 'another one' => [ 'param 1' => 7, 'param 2' => 8, 'param 3' => 9, ] ], 'errors' => [ 'form' => [ 'field 1' => [ 0 => 'error 1', 1 => 'error 2' ], 'field 2' => [ 0 => 'error 3', 1 => 'error 4 ' ] ], 'logic' => [ 0 => 'logic error 1', 1 => 'logic error 2' ] ], 0 => [ 0 => 'item 1', 1 => 'item 2' ], 1 => [ 0 => 'item 3', 1 => 'item 4' ], '123 - numeric containing' => [ 0 => 'item 5', 1 => 'item 6' ], 'not numeric containing' => [ 0 => 'item 5', 1 => 'item 6' ], ]; ``` 1. Leave/remove elements in/from `array.result\*` with keys containing only `one` or only `another`: ``` $map = [ 'result' => [ '/^(?:one|another)$/' => true ] ]; ``` 2. Leave/remove only elements in/from `array.errors.logic`: ``` $map = [ 'errors' => [ 'logic' => true ] ]; ``` 3. Leave/remove only elements with key `0` from `array.errors.form.field \*.\*`: ``` $map = [ 'errors' => [ 'form' => [ 'field \d+' => [ 0 => true ] ] ] ]; ``` 4. Leave/remove elements in/from `array.result.\*` with keys `param 3` and/or modify these elements' values by adding 5: ``` $map = [ 'result' => [ '/.+/' => [ 'param 3' => function($arg){ return $arg+=5; } ] ] ]; ``` ### Health Score 30 — LowBetter than 64% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity9 Limited adoption so far Community7 Small or concentrated contributor base Maturity72 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
