While we wait for typed properties to be implemented within PHP classes, let's have fun finding ways to implement this language feature on our own!
Install the Angle\Structure package via Composer:
composer require angle/structure
Structs are php classes that make the use of the Structure
trait. The trait will take over the class constructor, so make shure you use it only for strong typing properties (which structs are for basically).
<?php
namespace App\Structs;
use Angle\Structure\Structure;
use Carbon\Carbon;
class CarStruct
{
use Structure;
public $id = 0;
public $model = '';
public $mark = '';
public $range = 0;
public $power = 0.0;
public $createdAt = Carbon::class;
}
To create the struct, simply instantiate a new object with an array of properties:
<?php
use App\Structs\CarStruct;
$car = new CarStruct([
'id' => 12,
'model' => 'Model S',
'mark' => 'Tesla',
'range' => 315,
'power' => 560,
'createdAt' => Carbon::now(),
]);
If any of the parameters are not of expected value, the constructor will throw an InvalidArgumentException
error.
