In this library i provide the simple and easy way for working with enums.

,boolean
, etc.
<?php use Morilog\PhpEnum\Enum; final class CommentStatus extends Enum { const APPROVED = 1; const REJECTED = 2; const SOMETHING_ELSE = 3; }
Creating enum instances
By class constructor
<?php $status = new CommentStatus(1); $status->key(); // APPROVED $status->value(); // 1 $status->isApproved(); // true $status->isRejected(); // false
By camelCase
constant name
<?php $status = CommentStatus::rejected(); $status->key(); // REJECTED $status->value(); // 2 $status->isApproved(); // false $status->isRejected(); // true $other = CommentStatus::somethingElse(); $other->key(); // SOMETHING_ELSE $other->value(); // 3 $other->isApproved(); // false $other->isRejected(); // false $other->isSomethingElse(); // true
By fromKey()
method
<?php $status = CommentStatus::fromKey('APPROVED');
By fromValue()
method
<?php $status = CommentStatus::fromValue(1);
Static methods
<?php CommentStatus::keys(); // [APPROVED, REJECTED, SOMETHING_ELSE] CommentStatus::values(); // [1, 2, 3] CommentStatus::toArray(); // [APPROVED => 1, REJECTED => 2, SOMETHING_ELSE => 3]
Comparison enums
<?php $first = CommentStatus::approved(); $second = CommentStatus::rejected(); $third = CommentStatus::approved(); $first->equalsTo($second); // false $first->equalsTo($third); // true
