Regression: stripslashes/quoted_printable_* Reflection names str — Zend string; named args rejected (ext/standard/string.c)

Problem

Positional calls match Zend, but Reflection reports InternalArgInfo-style str instead of Zend stub string, and Zend-style named $string fails. Probed 2026-07-26 vs host Zend 8.2.32.

Repro	Zend 8.2	VM (2026-07-26)
Reflection (stripslashes)	string	str
Reflection (quoted_printable_encode/decode)	string	str
stripslashes(string: "a\\b")	"ab"	Unknown named parameter $string
quoted_printable_encode(string: "a=b")	"a=3Db"	Unknown named parameter $string

php-src reference

• php/php-src ext/standard/string.stub.php — stripslashes(string $string), quoted_printable_encode/quoted_printable_decode(string $string)

PHP implementation target

• lib/BuiltinParamNames.php — map each to ['string']
• Reflection + named-arg dispatch; PHP-in-PHP only; no new C

Repro

./script/docker-exec.sh -- bash -lc 'php bin/vm.php -r '\''try { echo stripslashes(string:"a\\b"), "\n"; } catch (Throwable $e) { echo $e->getMessage(), "\n"; }'\'''

Done when

• Reflection names use string
• Zend-style named calls match Zend on VM
• Compliance .phpt + test/repro/issue_NNNN_*.php
• php-src-strict; no php-compiler-strict shortcut

Merged via #23774.

Fix: lib/BuiltinParamNames.php — stripslashes, quoted_printable_encode, quoted_printable_decode now use Zend stub name string (was InternalArgInfo str).

Verification (Docker):

• php bin/vm.php test/repro/issue_23273_stripslashes_quoted_printable_named.php → ok
• vendor/bin/phpunit --filter testStripslashesQuotedPrintableZendStubNamedParams test/unit/BuiltinParamNamesAliasTest.php → OK (9 assertions)
• vendor/bin/phpunit --filter named_args_stripslashes_quoted_printable test/compliance/VMTest.php → OK (VM + JIT)
