How to uniformly manage PHP Enum?

                                                       

Install

composer require fangx/php-enum

Create

Use the ./vendor/bin/enum command to create an enumeration class.

./vendor/bin/enum FooEnum --enum="1=foo" --enum="b=bar" --path=Enums

This command creates a FooEnum.php in the Enums directory of the current directory by default. File. The file content is as follows:

<?phpnamespace Enums;use Fangx\Enum\AbstractEnum;class FooEnum extends AbstractEnum{
    const FOO = "f", __FOO = "foo";
    const BAR = "b", __BAR = "bar";}

Use

enumeration class to inherit by default \Fangx\Enum\AbstractEnum. The following methods can be called statically:

• toArray(Format $format = null, Filter $filter = null)
• toJson(Format $format = null, Filter $filter = null)
• desc($key, $default = 'Undefined')

Get all enumeration values

<?phpclass FooEnum extends \Fangx\Enum\AbstractEnum{
    const FOO = &#39;f&#39;, __FOO = &#39;foo&#39;;
    const BAR = &#39;b&#39;, __BAR = &#39;bar&#39;;}/**
 * [&#39;f&#39; => 'foo', 'b' => 'bar']
 */FooEnum::toArray();

Get the description information of the enumeration value

<?phpclass FooEnum extends \Fangx\Enum\AbstractEnum{
    const FOO = &#39;f&#39;, __FOO = &#39;foo&#39;;
    const BAR = &#39;b&#39;, __BAR = &#39;bar&#39;;}/**
 * "foo"
 */FooEnum::desc(&#39;f&#39;);/**
 * "bar"
 */FooEnum::desc(FooEnum::BAR);

Use format to constrain return values

<?phpclass FooFormat implements \Fangx\Enum\Contracts\Format{
    public function parse(\Fangx\Enum\Contracts\Definition $definition): array
    {
        return [[&#39;key&#39; => $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);

Use rules to filter enumeration values.

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);

Use custom collections as all The enumeration type, other usage methods are consistent with FooEnum.

<?phpclass BarEnum extends \Fangx\Enum\AbstractEnum{
    public function all()
    {
        return [
            new \Fangx\Enum\Definition('f', 'foo'),
            new \Fangx\Enum\Definition('b', 'bar'),
        ];
    }}
