Associative arrays render as if they were lists, so the keys are simply not shown:
phunkie > ["a" => 1, "b" => 2]
$var0: Array = [1, 2] <-- expected ["a" => 1, "b" => 2]
phunkie > ["x" => ["y" => 1]]
$var1: Array = [[1]] <-- nested too
EvaluationResult::formatArray() (src/Types/EvaluationResult.php:83) maps over values and discards keys:
private function formatArray(array $arr): string
{
$items = array_map(fn($v) => $this->formatValue($v), $arr);
return '[' . implode(', ', $items) . ']';
}This is misleading rather than merely terse: two different arrays print identically, and there is no way to tell from the output whether a key was a string or an integer. It matters most for the array functions people reach for in a REPL - array_first/array_last/array_find_key on an associative array all print results whose provenance is invisible.
Suggested: print key => value when the array is not a list (array_is_list()), and keep the current compact form when it is.
