Helper to reduce JSON objects size applying truncates on string fields using weights.

Requirements

• PHP >= 5.5

Install

Via Composer:

$ composer require rygilles/smart-json-reducer

Basic usage of smart-json-reducer

Important : The resulting JSON inner object values will be converted to array (Optimizations and fixes to come...)

The JSON string is not modified if the $maxSize size (in bytes) is not reached.

$weights parameter must be an array with "dot style" path as key and weight as value (normalized automatically).

The first version of this library doe not re-attribute gained space to others fields and final JSON string size will be significantly reduced. (Optimizations and fixes to come...)
