composer require fangx/php-enum
使用 ./vendor/bin/enum
命令建立一個列舉類.
./vendor/bin/enum FooEnum --enum="1=foo" --enum="b=bar" --path=Enums
該命令預設在 當前目錄的 Enums 目錄下建立一個 FooEnum.php 檔案. 檔案內容如下:
<?phpnamespace Enums;use FangxEnumAbstractEnum;class FooEnum extends AbstractEnum{ const FOO = "f", __FOO = "foo"; const BAR = "b", __BAR = "bar";}
列舉類預設繼承 FangxEnumAbstractEnum
. 可以靜態呼叫以下方法:
toArray(Format $format = null, Filter $filter = null)
toJson(Format $format = null, Filter $filter = null)
desc($key, $default = 'Undefined')
<?phpclass FooEnum extends FangxEnumAbstractEnum{ const FOO = 'f', __FOO = 'foo'; const BAR = 'b', __BAR = 'bar';}/** * ['f' => 'foo', 'b' => 'bar'] */FooEnum::toArray();
<?phpclass FooEnum extends FangxEnumAbstractEnum{ const FOO = 'f', __FOO = 'foo'; const BAR = 'b', __BAR = 'bar';}/** * "foo" */FooEnum::desc('f');/** * "bar" */FooEnum::desc(FooEnum::BAR);
<?phpclass FooFormat implements FangxEnumContractsFormat{ public function parse(FangxEnumContractsDefinition $definition): array { return [['key' => $definition->getKey() , 'value' => $definition->getValue()]]; }}class FooEnum extends FangxEnumAbstractEnum{ const FOO = 'f', __FOO = 'foo'; const BAR = 'b', __BAR = 'bar';}/** * [['key' => 'f', 'value' => 'foo'], ['key' => 'b', 'value' => 'bar'],] */$format = new FooFormat();FooEnum::toArray($format);
class FooFilter implements FangxEnumContractsFilter{ public function __invoke(FangxEnumContractsDefinition $definition) { return $definition->getKey() === 'f'; }}/** * ['f' => 'foo'] */$filter = new FooFilter();FooEnum::toArray(null, $filter);
FooEnum
一致.<?phpclass BarEnum extends FangxEnumAbstractEnum{ public function all() { return [ new FangxEnumDefinition('f', 'foo'), new FangxEnumDefinition('b', 'bar'), ]; }}
