Language: foreach(enum case) omits name/value props — Zend yields name (+ value if backed) (Zend/zend_enum.c)

Problem

Zend treats enum cases as objects with public properties name (unit + backed) and value (backed only). foreach ($case as $k => $v) yields those properties. The VM yields nothing.

Repro	Zend 8.2 (2026-07-26)	VM (2026-07-26)
unit foreach (E::A as ...)	name='A'	(empty)
backed foreach (S::A as ...)	name='A',value='x'	(empty)

php-src reference

• php/php-src Zend/zend_enum.c — enum case object properties name / value
• php/php-src Zend/zend_object_handlers.c — property iteration for internal objects

PHP implementation target

• Enum case property table / foreach path in lib/VM/ (enum support) — expose name and (for backed) value as public iterable props
• Keep get_object_vars($case) / property read parity with foreach
• No new C

Repro

./script/docker-exec.sh -- bash -lc 'cat >/tmp/repro_enum_foreach.php <<'"'"'PHP'"'"'
<?php
enum E { case A; }
$ks = [];
foreach (E::A as $k => $v) { $ks[] = "$k=" . var_export($v, true); }
echo implode(",", $ks), "\n";
enum S: string { case A = "x"; }
$ks = [];
foreach (S::A as $k => $v) { $ks[] = "$k=" . var_export($v, true); }
echo implode(",", $ks), "\n";
PHP
php /tmp/repro_enum_foreach.php
php bin/vm.php /tmp/repro_enum_foreach.php'

Done when

• Unit and backed enum case foreach match Zend property names/values
• Compliance .phpt under test/compliance/cases/language/
• php-src-strict

Preflight (mandatory):

• bootstrap-inventory: OK 6574/6574 (via release-readiness; local --check earlier saw docs drift — readiness regenerated path OK)
• spine-coverage: ok
• north-star5-fast: FAIL (gen-0 manifest/driver mismatch Self-host M5: bootstrap-inventory argv driver size floor — grow beyond 451KB stub #8713) — Pillar 1 known; not this issue's scope

Implementing enum case foreach name/value property iteration (php-src-strict).

[PurHur]

Merged via #23469 (970671d57).

Fix: collectObjectVarsForBuiltin early-returns EnumCaseSupport::objectVarsForCaseVariable for enum cases, so object foreach shares the get_object_vars / zend_enum.c name(+value) table.

Verification:

• Issue repro: Zend / bin/vm.php / bin/jit.php all print name='A' and name='A',value='x'
• phpunit --filter foreach_enum_case_properties OK
• Related foreach / get_object_vars enum compliance OK
