TraderInteractive Filter\Arrays

A filtering implementation for verifying correct data and performing typical modifications to arrays

Requirements

Requires PHP 7.0 or newer and uses composer to install further PHP dependencies. See the composer specification for more details.

Installation

filter-arrays-php can be installed for use in your project using composer. 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

Arrays::in

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

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

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]);
