Regression: touch() Reflection mtime/atime int — Zend ?int (ext/standard/file.stub.php)

Problem

ReflectionFunction('touch') reports $mtime / $atime as int with default NULL. php-src / Zend declare ?int $mtime = null / ?int $atime = null (ext/standard/file.stub.php). Nullable Reflection types matter for static analysis and named-arg tooling.

Probed 2026-08-07 @ fdf529e8bd (VM vs host Zend 8.2.32 / stub PHP-8.4.11).

Param	Zend / php-src	VM
mtime	?int default null	int default NULL
atime	?int default null	int default NULL

php-src reference

• php/php-src ext/standard/file.stub.php — function touch(string $filename, ?int $mtime = null, ?int $atime = null): bool

PHP implementation target

• Builtin Reflection metadata for touch in ext/standard/ / VM introspection — nullable int params
• PHP-in-PHP; no new C

Repro

./script/docker-exec.sh -- bash -lc 'php bin/vm.php -r '"'"'
$r=new ReflectionFunction("touch");
foreach ($r->getParameters() as $p) {
  echo $p->getName(), ":", ($p->hasType()?(string)$p->getType():"-"), "\n";
}
'"'"''
# Expect: mtime:?int / atime:?int
# Actual: mtime:int / atime:int

Done when

• Reflection param types are ?int matching Zend
• Runtime touch($f, null, null) still matches Zend
• Compliance/unit guard; php-src-strict
