See the [composer specification](composer.json) for more details. Installation ------------ [](#installation) filter-arrays-php can be installed for use in your project using [composer](http://getcomposer.org). The recommended way of using this library in your project is to add a `composer.json` file to your project. The following contents would add filter-arrays-php as a dependency: ``` composer require traderinteractive/filter-arrays ``` Included Filters ---------------- [](#included-filters) #### Arrays::copy [](#arrayscopy) This filter will copy values from the input array into the resulting array using the destination key map. ``` $input = ['foo' => 1, 'bar' => 2]; $keyMap = ['FOO_VALUE' => 'foo', 'BAR_VALUE' => 'bar']; $result = \TraderInteractive\Filter\Arrays::copy($input, $keyMap); assert($result === ['FOO_VALUE' => 1, 'BAR_VALUE' => 2]); ``` #### Arrays::copyEach [](#arrayscopyeach) This filter will copy values from each array within the input array into the resulting array using the destination key map. ``` $input = [ ['foo' => 1, 'bar' => 2], ['foo' => 3, 'bar' => 4], ]; $keyMap = ['FOO_VALUE' => 'foo', 'BAR_VALUE' => 'bar']; $result = \TraderInteractive\Filter\Arrays::copyEach($input, $keyMap); assert($result === [['FOO_VALUE' => 1, 'BAR_VALUE' => 2], ['FOO_VALUE' => 3, 'BAR_VALUE' => 4]]); ``` #### Arrays::in [](#arraysin) This filter is a wrapper around `in_array` including support for strict equality testing. The following does a strict check for `$value` against the 3 accepted values. ``` \TraderInteractive\Filter\Arrays::in($value, ['a', 'b', 'c']); ``` #### Arrays::filter [](#arraysfilter) This filter verifies that the argument is an array and checks the length of the array against bounds. The default bounds are 1+, so an empty array fails by default. The following checks that the `$value` is an array with exactly 3 elements. ``` \TraderInteractive\Filter\Arrays::filter($value, 3, 3); ``` #### Arrays::flatten [](#arraysflatten) This filter flattens a multi-dimensional array to a single dimension. The order of values will be maintained, but the keys themselves will not. For example: ``` $value = \TraderInteractive\Filter\Arrays::flatten([[1, 2], [3, [4, 5]]]); assert($value === [1, 2, 3, 4, 5]); ``` #### Arrays::implode [](#arraysimplode) This filter is a wrapper to the PHP `implode` function. It joins an array of strings with the optional glue string. ``` $value = \TraderInteractive\Filter\Arrays::implode(['lastname', 'email', 'phone'], ','); assert($value === 'lastname,email,phone'); ``` #### Arrays::pad [](#arrayspad) This filter pads an array to the specified length with a value. Padding optionally to the front or end of the array. ``` $value = \TraderInteractive\Filter\Arrays::pad([1, 2], 5, 0, \TraderInteractive\Filter\Arrays::ARRAY_PAD_FRONT); assert($value === [0, 0, 0, 1, 2]); ``` #### Arrays::unique [](#arraysunique) This filter removes any duplicate values in the given array. Optionally throwing an exception if duplicate values are found. ``` $value = \TraderInteractive\Filter\Arrays::unique(['foo', 'bar', 'foo']); assert($value === ['foo', 'bar']); ``` Project Build ------------- [](#project-build) With a checkout of the code get [Composer](http://getcomposer.org) in your PATH and run: ``sh composer install ./vendor/bin/phpunit ./vendor/bin/phpcs ``` For more information on our build process, read through out our [Contribution Guidelines](./.github/CONTRIBUTING.md). ``` ### Health Score 40 — FairBetter than 86% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity34 Limited adoption so far Community19 Small or concentrated contributor base Maturity72 Established project with proven stability Bus Factor1 Top contributor holds 81.8% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
