Description:
------------
I have a class with a static property of type array. This array starts with a key/value pair with a
numeric key (value 1 defined in a constant) used to start the indexing. After that, just another two
values, expecting the keys to be autogenerated after the initial index.
I expect the array keys to be correlative starting from 1, and to 3. But the array has only two keys
starting from 0, and to 1.
I attached a test script, for the script I expect the output to be:
array (
1 => 'first',
2 => 'second',
3 => 'third',
)
but, instead I get:
array (
0 => 'second',
1 => 'third',
)
I tested it using [] and array() and get the same results.
It only happens when using self:: followed by constant name as first key in the static property, the
next two code portions works as expected, both inside or outside of the class:
$arr = array(
1 => 'a',
'b',
'c'
);
$arr = array(
Test::FIRST => 'd',
'e',
'f'
);
Test script:
---------------
class Test
{
const FIRST = 1;
const SECOND = 2;
const THIRD = 3;
protected static $array = [
self::FIRST => 'first',
'second',
'third'
];
public function __construct()
{
var_export(self::$array);
}
}
$test = new Test();
Expected result:
----------------
array (
1 => 'first',
2 => 'second',
3 => 'third',
)
Actual result:
--------------
array (
0 => 'second',
1 => 'third',
)
