范例
Example #1 SplEnum usage example
<?phpclass Month extends SplEnum { const __default = self::January; const January = 1; const February = 2; const March = 3; const April = 4; const May = 5; const June = 6; const July = 7; const August = 8; const September = 9; const October = 10; const November = 11; const December = 12;}echo new Month(Month::June) . PHP_EOL;try { new Month(13);} catch (UnexpectedValueException $uve) { echo $uve->getMessage() . PHP_EOL;}?>
以上例程会输出：
