Deprecation Notices in PHP 8.3

[underrobyn]

Hi,

Running PHP 8.3.0:

PHP 8.3.0 (cli) (built: Nov 21 2023 17:48:31) (ZTS Visual C++ 2019 x64)

I am getting Deprecation notices when trying to fetch combinations using the following code:

$galaxyIDs = array_keys($galaxies);
print_r($galaxyIDs);

$galaxyCombinations = new Combinations($galaxyIDs, 2);
print_r($galaxyCombinations->toArray());

The output of the code is:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
    [7] => 8
    [8] => 9
)
