Stdlib: get_class() on enum case must return enum name not false (ext/standard/basic_functions.c)

Problem

get_class() on an enum case must return the enum class name (e.g. "E"). Issue filed when VM returned false.

Maintainer re-probe (2026-06-06): VM now returns string(1) "E" — matches Zend on php bin/vm.php -r 'enum E { case A; } var_dump(get_class(E::A));'. Remaining work is to lock parity in compliance tests and verify JIT/AOT paths (if they bypass get_class() VM handler).

php-src reference

• php/php-src ext/standard/basic_functions.c — zif_get_class() enum branch
• php/php-src Zend/zend_enum.c — enum object class name

Related: #4260 (get_debug_type() on enum cases) — separate builtin, same enum-case object path.

Repro

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php bin/vm.php -r "enum E { case A; } var_dump(get_class(E::A));"
php -r "enum E { case A; } var_dump(get_class(E::A));"
php bin/jit.php -r "enum E { case A; } var_dump(get_class(E::A));" 2>&1

Check	Zend	VM (2026-06-06)	JIT
get_class(E::A)	"E"	"E" ✓	verify
get_class($object) plain object	class name	unchanged	verify
get_class() no args in method scope	$this class	unchanged	verify

Add test/repro/parity_get_class_enum.php (or move from test/repro-maintainer/ if present).

Scope (this repo)

Path	Work
ext/standard/get_class_.php	Confirm enum-case branch
ext/standard/VmReflection.php	Enum case class-id resolution
lib/JIT/Builtin/	JIT lowering if missing
test/compliance/cases/stdlib/get_class_enum.phpt	VM + JIT + AOT

Done when

• Compliance .phpt green on VM, JIT, AOT
• get_class() with no args / two args edge cases on enum cases unchanged vs Zend
• Close this issue once tests land (VM fix appears present)

Merged in #7944.

Verification (Docker):

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php test/repro/parity_get_class_enum.php
php bin/vm.php test/repro/parity_get_class_enum.php
php bin/jit.php test/repro/parity_get_class_enum.php
vendor/bin/phpunit --filter get_class_enum test/compliance/ test/aot/AotTest.php
'

All paths return enum class name (E, Status) for enum case operands; VM/JIT/AOT compliance tests added. No code changes required — get_class_.php TYPE_ENUM_CASE branch and JitGetClass were already correct.
