reichwebconsulting/array-filters
================================

[](#reichwebconsultingarray-filters)

reichwebconsulting/array-filters is a PHP 7.1+ library for array filtering.

This project began as part of a hydration/extraction library, but I realized the components had broad use across numeric projects I work on. The library contains an interface called `FilterInterface` that describes an interface for passing arrays and returning modified versions of those arrays.

The `ExcludeFieldsFilter` provides the ability to remove key/value pairs from the input array by specifying keys to exclude. This filter is useful when you have an array of data to return but need to filter out sensitive fields based on the context. For example, `ExcludeFieldsFilter` could be used to filter out the "password" and "email" fields from user records before returning them in a result set.

The `KeyMutatorFilter` provides the ability to modify array keys based on any logic you code into a `callable` function you assign to the filter. The output array will contain all of the same values as the input array, but assigned to keys generates using the configured callback function. The `KeyMutatorFilter` is useful when you have an array of data whose keys need to be in a slightly different format before they are useful for the next phase of code. A good example is when PostgreSQL result sets, whose properties are all lowercase--a convention that is rarely followed within PHP.

The `KeyPrefixFilter` provides the ability to add prefixes to all of the array keys. A great use case for `KeyPrefixFilter` is when you have a result set you would like to map onto a `PDOStatement` parameter list. PDO parameters begin with a colon, so just use KeyPrefixFilter to add a colon to your keys before using the array as your PDO statement parameters.
