Is it possible to use SplEnum in php 5.2.6?

Cédric picture Cédric · Jul 27, 2011 · Viewed 9k times · Source

I tried to use class :

abstract class my_abstractEnum extends SplEnum {
...
}

and

class my_categoryEnum extends my_abstractEnum {
...
}

and I have :

Fatal error: Class 'SplEnum' not found

I work on PHP 5.2.6. SplEnum is for php > 5.3 ? I don't see so in the documentation ...

SplTypes is an experimental PECL Extension. You have to install it with pecl install SPL_Types from the command line. There is no DLL for windows, so you are limited to Linux (or have to build your own).

An alternative in userland can be found in http://www.whitewashing.de/2009/08/31/enums-in-php.html
