文档

安装

需要 composer

composer.json (注意:将 dev-main 替换为 版本约束,例如 ^3.0 - 请参阅 版本 以获取有效版本)

{
	"require": {
		"php": "^8.1",
		"chillerlan/php-settings-container": "dev-main"
	}
}

盈利!

用法

SettingsContainerInterface (包裹在 SettingsContainerAbstract 中)为不可变对象属性提供插件功能,并添加一些额外功能,如加载/保存JSON、数组等。它接受一个 iterable 作为唯一的构造函数参数,并在调用时对每个使用的特性调用具有特性名称的方法(MyTrait::MyTrait())。

可以在 rules-magic-access.neon 中找到排除由在 SettingsContainerInterface 上访问魔法属性而产生的PHPStan规则集。

简单用法

class MyContainer extends SettingsContainerAbstract{
	protected string $foo;
	protected string $bar;
}
// use it just like a \stdClass (except the properties are fixed)
$container = new MyContainer;
$container->foo = 'what';
$container->bar = 'foo';

// which is equivalent to
$container = new MyContainer(['bar' => 'foo', 'foo' => 'what']);
// ...or try
$container->fromJSON('{"foo": "what", "bar": "foo"}');


// fetch all properties as array
$container->toArray(); // -> ['foo' => 'what', 'bar' => 'foo']
// or JSON
$container->toJSON(); // -> {"foo": "what", "bar": "foo"}
// JSON via JsonSerializable
$json = json_encode($container); // -> {"foo": "what", "bar": "foo"}

//non-existing properties will be ignored:
$container->nope = 'what';

var_dump($container->nope); // -> null

高级用法

// from library 1
trait SomeOptions{
	protected string $foo;
	protected string $what;

	// this method will be called in SettingsContainerAbstract::construct()
	// after the properties have been set
	protected function SomeOptions():void{
		// just some constructor stuff...
		$this->foo = strtoupper($this->foo);
	}

	/*
	 * special prefixed magic setters & getters
	 */

	// this method will be called from __set() when property $what is set
	protected function set_what(string $value):void{
		$this->what = md5($value);
	}

	// this method is called on __get() for the property $what
	protected function get_what():string{
		return 'hash: '.$this->what;
	}
}

// from library 2
trait MoreOptions{
	protected string $bar = 'whatever'; // provide default values
}
$commonOptions = [
	// SomeOptions
	'foo' => 'whatever',
	// MoreOptions
	'bar' => 'nothing',
];

// now plug the several library options together to a single object
$container = new class ($commonOptions) extends SettingsContainerAbstract{
	use SomeOptions, MoreOptions;
};

var_dump($container->foo); // -> WHATEVER (constructor ran strtoupper on the value)
var_dump($container->bar); // -> nothing

$container->what = 'some value';
var_dump($container->what); // -> hash: 5946210c9e93ae37891dfe96c3e39614 (custom getter added "hash: ")

免责声明

这可能是一个绝妙的想法,也可能是一个完全愚蠢的想法 - 由你决定。然而,我喜欢它并且它有效。此外,这不是一个依赖注入容器。请停止使用DI容器。
