Introduction
Hydrators insert an array of data into object properties (this is called "hydrating") and convert object properties back to an array (this is called "extracting"). Hydrators are often used in the context of Forms, with the binding functionality of Laminas, but can also be used in any hydrating/extracting context (for instance, it can be used in RESTful context). For an introduction to hydrators, please read Laminas hydrator documentation.
