装置
composer require fangx/php-enum
创立
应用 ./vendor/bin/enum
饬令创立一个枚举类.
./vendor/bin/enum FooEnum --enum="1=foo" --enum="b=bar" --path=Enums
该饬令默许正在 以后目次的 Enums 目次下创立一个 FooEnum.php 文件. 文件内容以下:
<?phpnamespace Enums;use Fangx\Enum\AbstractEnum;class FooEnum extends AbstractEnum{ const FOO = "f", __FOO = "foo"; const BAR = "b", __BAR = "bar";}
应用
枚举类默许承继 \Fangx\Enum\AbstractEnum
. 能够动态挪用如下办法:
toArray(Format $format = null, Filter $filter = null)
toJson(Format $format = null, Filter $filter = null)
desc($key, $default = 'Undefined')
猎取一切的枚举值
<?phpclass FooEnum extends \Fangx\Enum\AbstractEnum{ const FOO = 'f', __FOO = 'foo'; const BAR = 'b', __BAR = 'bar';}/** * ['f' => 'foo', 'b' => 'bar'] */FooEnum::toArray();
猎取枚举值的形容信息
<?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);
应用格局来束缚前往值
<?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);
经过规定来过去过滤枚举值.
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);
应用自界说的荟萃来作为一切的枚举类型, 其余应用办法与 FooEnum
分歧.
<?phpclass BarEnum extends \Fangx\Enum\AbstractEnum{ public function all() { return [ new \Fangx\Enum\Definition('f', 'foo'), new \Fangx\Enum\Definition('b', 'bar'), ]; }}
