A PHP 7+ enumeration library.
To create perfect enums for PHP library
composer require "paillechat/php-enum:^2.0"
Declare enum class by extending basic Enum and filling it with constants.
Constant value does not matter. You can fill it with any payload you can utilize as
general constant, but we suggest you to keep constants as protected as possible
<?phpusePaillechat\Enum\Enum;
/** * These docs are used only to help IDE * * @method static static ONE * @method static static TWO */class IssueType extends Enum {
protectedconstONE = 1;
protectedconstTWO = 2;
} # Now you can create enum via named static call/** @var Enum $one */$one = IssueType::ONE();
# Enums keeps strict equality$one1 = IssueType::ONE();
$one2 = IssueType::ONE();
$two = IssueType::TWO();
$one1 === $one2;
$one !== $two;
# Enums plays well with built-in functions\in_array(IssueType::ONE(), [$one, $two], true);
# Enums plays well with signature type checksfunctionmoveIssue(IssueType$type) {
if ($type === IssueType::ONE()) {
thrownew \LogicException();
}
// ....
}
# You can convert enum to name and back$name = $one->getName();
$new = IssueType::$name();
