Feel free to store it anywhere you like, such as App\DataTransferObjects or even in the same directory as your models.Īlso note that we're not limited to primitive types here - we can include other classes including nested data transfer objects. I like to store these in App\Values because I'll typically be adding domain-specific methods that make it more like a value object than a plain DTO. Use Spatie\DataTransferObject\DataTransferObject Ĭlass Address extends DataTransferObject implements Castable We just need to define the properties: namespace App\Values
It handles casting the raw array to and from an instance of our custom class. The data is validated to make sure it conforms to a defined structure and types, otherwise an exception is thrown. How can we take it even further, beyond the docs?ĭo you know what makes working with array structures in PHP even nicer? Spatie's Data Transfer Object (DTO) package, that's what! composer require spatie/data-transfer-object Our custom cast could wrap these and instantiate our value object and things would be pretty sweet. Public static function castUsing(array $arguments)Īnd now we can cast to the value object class itself, instead of the custom cast, which just feels a bit nicer: use App/Values/Address Īs for the cast logic, serializing between JSON and arrays or stdClass objects is pretty straight-forward with json_encode() and json_decode(). Use Illuminate\Contracts\Database\Eloquent\Castable Now imagine casting to an instance of a specific value object class via Laravel's custom casts: namespace App\Models īut take that another step and make the value object class castable by implementing the Castable interface: namespace App\Values This is cool too, but in practice I've found an associative array is often easier to work with. This does the same thing, but for a stdClass object. You may also be familiar with: namespace App\Models This will automatically cast an array (associative or numeric) to JSON, and back again. You may be familiar with the following built-in cast: namespace App\Models So what are our options for working with JSON columns in Laravel? And modern database engines can index and natively query inside these JSON structures quite well. JSON columns effectively give us the benefits (and downsides) of a NoSQL/document-based database inside our relational database. There are plenty of reasons why you may want to consider a JSON column. Maybe we have a collection of items that aren't deserving of their own table. The Laravel docs has an excellent example of how we can cast to and from multiple columns into a single value object.īut in some cases we may want a nested structure, or maybe we have a lot of optional fields that we don't want cluttering the table structure. We could create dedicated columns in the database for each attribute. However, the database won't be able to query the parts easily, and depending on the number of type of attributes, it could get unwieldy. So we may be tempted to create our own conventions. We may not always be so lucky with our value objects though. #Php json decode stdclass object how to
For example, a date can represent the year, month, and day as Y-m-d but we can still pull it apart if needed, and the database knows how to query the parts individually. Some may have have special formats that allow us to represent the individual attributes as a single string. That's part of what separates them from primitive types like strings and integers. Most value objects have multiple attributes. Now, if we call the $jsonDecoded variable just as you would with an associative array, we will get the values from the parsed-associative array.Have you ever wanted to access an attribute of an Eloquent model as a value object, similar to how Eloquent lets us work with dates via Carbon? $user->address->calculateDistance($otherUser->address)
#Php json decode stdclass object code
So, we have our JSON, how do we decode it if it’s contained in a string variable? Let’s see the following code for instance – }] Parsing JSON with json_encode Parse JSON to Object Credit to Mocakroo for random data generation! The function we are going to talk about today is json_decode which essentially lets you parse JSON into a usable format.įirstly, we are going to need some JSON. Native PHP has got two helpful functions, json_encode & json_decode. json file, from an API or are passing data from PHP controllers to a view, then PHP is ready.
