A trait to give class attributes
- Give class attributes with array.
- Define attributes strict type.
Just use HasAttributes trait and pass key value array to constructor
class Post
{
use \Clouding\HasAttributes\HasAttributes;
}
$post = new Post([
'title' => 'Hello',
'body' => 'World',
]);
echo $post->title; // Hello
echo $post->body; // Worldcomposer require clouding/has-attributes
Declare $define to define type
require 'vendor/autoload.php';
interface Eatable {}
class Pig implements Eatable { }
class Zoo
{
use \Clouding\HasAttributes\HasAttributes;
protected $define = [
'name' => 'string',
'number' => 'int',
'animal' => Eatable::class,
];
}
$zoo = new Zoo([
'name' => 'Mike',
'number' => 100,
'animal' => new Pig(),
]);
echo $zoo->name; // Mike
echo $zoo->number; // 100
echo get_class($zoo->animal); // PigIf you declare $define property, it will check type strictly
new Zoo(['name' => 999]);
// InvalidArgumentException: [name => 999] value is not equal to define type [string] And can't set key that is not defined
new Zoo(['foo' => 'bar']);
// InvalidArgumentException: Key [foo] is not defined Supported $define type:
stringint,integerbool,booleanobjectarrayreal,float,double- Class, Interface
There have many way to set attributes
class Person
{
use \Clouding\HasAttributes\HasAttributes;
}
$person = new Person([
'id' => 100,
]);
$person->setAttributes([
'name' => 'Marry',
'phone' => '0912345678'
]);
$person->setAttribute('sex', 'female');
$person->age = 18;
echo $person->id; // 100
echo $person->name; // Marry
echo $person->phone; // 0912345678
echo $person->sex; // female
echo $person->age; // 18class Person
{
use \Clouding\HasAttributes\HasAttributes;
}
$person = new Person([
'id' => 100,
'name' => 'Jack',
]);
echo $person->getAttribute('id'); // 100
echo $person->getAttribute('salary', 0); // 0 (if key not exists return default value)
var_dump($person->getAttributes('id', 'name')); // ['id' => 100, 'name' => 'Jack']
var_dump($person->getAttributes(['id', 'name'])); // ['id' => 100, 'name' => 'Jack']
