reichwebconsulting/array-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.
