[Editor's note: that is already possible as of PHP 5.6.0.]
Note, as of PHP7 it is possible to define class constants with an array.
<?php
class MyClass
{
const ABC = array('A', 'B', 'C');
const A = '1';
const B = '2';
const C = '3';
const NUMBERS = array(
self::A,
self::B,
self::C,
);
}
var_dump(MyClass::ABC);
var_dump(MyClass::NUMBERS);
// Result:
/*
array(3) {
[0]=>
string(1) "A"
[1]=>
string(1) "B"
[2]=>
string(1) "C"
}
array(3) {
[0]=>
string(1) "1"
[1]=>
string(1) "2"
[2]=>
string(1) "3"
}
*/
?>
