php and enumerations

im puzzled. i use vbscript and c++ etc and they have enumerations. i can't find how to create an enum in php, does anyone have any ideas? i looked in the manual..no hope. i want something like this

var $myEnum {0 = 'red', 1 = 'blue', 2 = 'yellow'};
$d = new myEnum('blue');

i suppose i could use a class but its a waste if php does actually support enums.

Can you just use an array?

Consider:
$myEnum = array ("red","blue","yellow");
$d = $myEnum[1];

or maybe an associative array?




I didn't see any direct references to enums in the PHP manual but I've never had much use for them...

i guess i could yeah...but im assuming that no one knows if php supports enums? if not its ok...an associative array will do. thanks guys

ENUM's don't exists in PHP. No real need for them, as PHP's arrays can pretty much handle the job.

I got to this thread trying to find out the same thing. I didn't really get my question answered, but I did think of a nasty workaround.

Hey all,

This is how I implement enumeration in php. It is a little tighter then using an array so you have less bugs later.

I can't post the link but you can look it up detailed explanation on my blog at wordpress. wshell.wordpress.com

Here is the code...



Working Example Using Constructor:

$shape = new Shape("Circle");
echo $shape->Value();

Output: Circle

Working Example Using Set():

$shape = new Shape();
$shape->Set("Square");
echo $shape->Value();

Output: Square

Exception Example Using Set():

$shape = new Shape();
$shape->Set("Trapazoid");
echo $shape->Value();

Output: Enumeration Exception.

Enjoy!
