Regression: get_defined_functions(exclude_disabled:) — unknown named parameter on reference profile (re-#4942, ext/standard/basic_functions.c)

Problem

Zend 8.2 accepts get_defined_functions(exclude_disabled: true) and returns the usual ['internal'=>…,'user'=>…] shape. On the php-compiler VM (reference profile, no PHP_COMPILER_PROFILE), the same call fatals with unknown named parameter — the builtin is registered with zero parameters.

Repro	Zend 8.2+	VM (2026-07-06)
get_defined_functions(exclude_disabled: true)	callable, array shape	Error: Unknown named parameter $exclude_disabled ❌

php-src reference

• php/php-src ext/standard/basic_functions.c — PHP_FUNCTION(get_defined_functions) / $exclude_disabled filter

PHP implementation target

• ext/standard/ builtin registration + VmReflection / get_defined_functions handler — accept optional exclude_disabled bool on profiles where Zend advertises it; filter disabled internal symbols like php-src
• lib/CompilerVersion.php — profile gate must match Zend function_exists/signature on reference profile

Repro

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh && php bin/vm.php test/repro/maintainer_gap_get_defined_functions_exclude_disabled_reference.php'
# fail: Error: Unknown named parameter $exclude_disabled

Done when

• get_defined_functions(exclude_disabled: true) callable on reference profile; shape matches Zend
• Compliance .phpt guard under test/compliance/cases/stdlib/
• php-src-strict; no php-compiler-strict shortcut

claim: cursor-agent-lane-a — starting this run (reference profile gate fix).

Merged via #16910.

Fix: supportsGetDefinedFunctionsExcludeDisabled() now gates on REFERENCE_PHP_VERSION >= 8.2 (Zend exposes exclude_disabled on reference profile) instead of tying to PHP 8.4-only get_declared_* exclude_deprecated.

Verification:

• php bin/vm.php test/repro/maintainer_gap_get_defined_functions_exclude_disabled_reference.php → ok
• vendor/bin/phpunit --filter get_defined_functions_exclude_disabled test/compliance/VMTest.php → OK (2 tests)
• vendor/bin/phpunit --filter testSupportsGetDefinedFunctionsExcludeDisabled test/unit/CompilerVersionGateTest.php → OK (2 tests)

Merged via #16911.

Root cause: supportsGetDefinedFunctionsExcludeDisabled() was aliased to the PHP 8.4-only get_declared_* gate, but Zend 8.2+ accepts get_defined_functions(exclude_disabled:) (positional and named).

Fix: Always enable the parameter on reference profile; fix JIT compileTimeBool for AOT.

Verification: VM repro + compliance (2 tests) + AOT fixture green.
