Stdlib: pathinfo() PATHINFO_* named flag constants rejected — LogicException not basename/filename (ext/standard/basic_functions.c)

Problem

pathinfo() second argument cannot accept PATHINFO_* named constants—the VM throws LogicException: pathinfo() flags must be an integer in this compiler build instead of returning the selected component.

Call	Zend	VM today
pathinfo('/foo/bar/baz.txt', PATHINFO_FILENAME)	'baz'	LogicException
pathinfo('/foo/bar/baz.txt', PATHINFO_EXTENSION)	'txt'	LogicException
pathinfo('/foo/bar/baz.txt', PATHINFO_BASENAME)	'baz.txt'	LogicException

Integer flag values work when written literally; named constants are not lowered to their integer values at the builtin boundary.

php-src reference

• php/php-src ext/standard/basic_functions.c — zif_pathinfo, PATHINFO_* bitmask flags

Repro

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh && php bin/vm.php test/repro/maintainer_gap_pathinfo_pathinfo_filename.php'
php bin/vm.php test/repro/maintainer_gap_pathinfo_pathinfo_filename.php

Implementation hints (PHP-in-PHP)

• ext/standard/pathinfo.php — resolve PATHINFO_DIRNAME|BASENAME|EXTENSION|FILENAME|ALL constants like Zend
• Share constant-int builtin arg helper with sort/round fixes (Stdlib: ksort()/asort() inline SORT_* flag expressions rejected at runtime (ext/standard/array.c) #9278, Stdlib: join()/implode() empty [] literal — TypeError null for $array not empty string (ext/standard/string.c) #9563)
• Stdlib: pathinfo() — PATHINFO_ALL must return associative array with dirname/basename/extension/filename (ext/standard/basic_functions.c parity) #4225 tracks PATHINFO_ALL associative shape—orthogonal; this issue is named-constant binding for single-flag calls

Done when

• Repro script matches Zend on all three lines
• No LogicException for PATHINFO_FILENAME et al.
• Compliance guard added
• JIT/AOT pathinfo flags agree

claim released: cursor-agent-lane-B — repro green on master (PATHINFO_* constants work); pathinfo_flags.phpt passes. Recommend close.

claim released: PATHINFO_* constants green on master — pathinfo_flags.phpt passes; Zend/VM match on issue repro paths.

claim: PHP Compiler STD Lib Advanced — batch (issues #9565, #9620)

[PurHur]

Merged via #16531 — pathinfo($path, flags: PATHINFO_*) now resolves named flags via BuiltinParamNames. Verified: repro + pathinfo_named_flags.phpt green on VM.
