    <p>My data arrives in the form of associative arrays. This works, but my code is a mess of nested arrays and I would like to start using proper OO/Objects to make this data easier to work with. I cannot change the way I receive this data, so I would like to find a clean way to convert the associative arrays into instances of my classes below.</p> <p>I have these classes to model People in my application:</p> <pre><code>class Person { /** * @var string */ private $_name; /** * @var array[Dog] */ private $_dogs = array(); /** * @var array[Hobby] */ private $_hobbies = array(); } class Dog { /** * @var string */ private $_color; /** * @var string */ private $_breed; } class Hobby { /** * @var string */ private $_description; /** * @var int */ private $_cost; } </code></pre> <p>My data (in JSON) looks like this:</p> <pre><code>'person': { 'name': 'Joe', 'dogs': [ {'breed': 'Husky', 'color': 'Black'}, {'breed': 'Poodle', 'color': 'Yellow'} ] 'hobbies': [ {'description': 'Skiing', 'cost': 500}, {'description': 'Running', 'cost': 0} ] } </code></pre> <p>I can easily convert this JSON to an associative array using <code>json_decode</code>, but the difficulty comes in converting each of the nested <code>Hobby</code> and <code>Pet</code> objects into the appropriate classes, and then when I want the associative array back, converting these objects into associative arrays again.</p> <p>I can do all this by writing a to/from array function in each of my classes but that seems rather messy and prone to error. Is there a more straightforward way that I can quickly hydrate/dehydrate these objects?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
