granam / boolean-enum

Enumeration with booleans only

Enumeration with boolean values

Usage

1. Use enum
2. NULL is NULL, not Enum
3. Installation

Use enum

<?php
use \Granam\BooleanEnum\BooleanEnum;

$enum = BooleanEnum::getEnum(true);
echo $enum->getValue(); // 1
var_dump($enum->getValue()); // (bool) true
var_dump($enum->is(true)); // true
var_dump($enum->is(false)); // false
var_dump($enum->is(1)); // false
var_dump($enum->is($enum)); // true

NULL is NULL, enum can not hold it

You can not create BooleanEnum with NULL value. Just use NULL directly for such value.

<?php
try {
    \Granam\BooleanEnum\BooleanEnum::getEnum(null);
} catch(\Granam\BooleanEnum\Exceptions\UnexpectedValueToConvert $unexpectedValueToConvert) {
    echo $unexpectedValueToConvert->getMessage(); // Expected boolean or object with __toString method on strict mode, got NULL
}
