composer require fangx/php-enum
使用 ./vendor/bin/enum 命令创建一个枚举类.
./vendor/bin/enum FooEnum --enum="1=foo" --enum="b=bar" --path=Enums
该命令默认在 当前目录的 Enums 目录下创建一个 FooEnum.php 文件. 文件内容如下:
<?phpnamespace Enums;use Fangx\Enum\AbstractEnum;class FooEnum extends AbstractEnum{
const FOO = "f", __FOO = "foo";
const BAR = "b", __BAR = "bar";}枚举类默认继承 \Fangx\Enum\AbstractEnum. 可以静态调用以下方法:
toArray(Format $format = null, Filter $filter = null)toJson(Format $format = null, Filter $filter = null)desc($key, $default = 'Undefined')<?phpclass FooEnum extends \Fangx\Enum\AbstractEnum{
const FOO = 'f', __FOO = 'foo';
const BAR = 'b', __BAR = 'bar';}/**
* ['f' => 'foo', 'b' => 'bar']
*/FooEnum::toArray();<?phpclass FooEnum extends \Fangx\Enum\AbstractEnum{
const FOO = 'f', __FOO = 'foo';
const BAR = 'b', __BAR = 'bar';}/**
* "foo"
*/FooEnum::desc('f');/**
* "bar"
*/FooEnum::desc(FooEnum::BAR);<?phpclass FooFormat implements \Fangx\Enum\Contracts\Format{
public function parse(\Fangx\Enum\Contracts\Definition $definition): array
{
return [['key' => $definition->getKey() , 'value' => $definition->getValue()]];
}}class FooEnum extends \Fangx\Enum\AbstractEnum{
const FOO = 'f', __FOO = 'foo';
const BAR = 'b', __BAR = 'bar';}/**
* [['key' => 'f', 'value' => 'foo'], ['key' => 'b', 'value' => 'bar'],]
*/$format = new FooFormat();FooEnum::toArray($format);class FooFilter implements \Fangx\Enum\Contracts\Filter{
public function __invoke(\Fangx\Enum\Contracts\Definition $definition)
{
return $definition->getKey() === 'f';
}}/**
* ['f' => 'foo']
*/$filter = new FooFilter();FooEnum::toArray(null, $filter);FooEnum 一致.<?phpclass BarEnum extends \Fangx\Enum\AbstractEnum{
public function all()
{
return [
new \Fangx\Enum\Definition('f', 'foo'),
new \Fangx\Enum\Definition('b', 'bar'),
];
}}
