Regression: htmlspecialchars_decode/html_entity_decode Reflection names quote_style — Zend flags; named args rejected (ext/standard/basic_functions.stub.php)

Problem

HTML entity decode helpers still advertise legacy quote_style instead of Zend stub flags, so flags: named calls fail (and $string also fails when paired). Positional calls match. Probed 2026-07-26 vs host Zend 8.2.32.

Repro	Zend 8.2	VM (2026-07-26)
Reflection htmlspecialchars_decode	string,flags	string,quote_style
Reflection html_entity_decode	string,flags,encoding	string,quote_style,encoding
htmlspecialchars_decode(string: "&", flags: ENT_QUOTES)	"&"	Unknown named parameter $string (or $flags if string positional)
html_entity_decode(string: "&", flags: ENT_QUOTES)	"&"	Unknown named parameter $string

php-src reference

• php/php-src ext/standard/basic_functions.stub.php — htmlspecialchars_decode(string $string, int $flags = …), html_entity_decode(string $string, int $flags = …, ?string $encoding = null)

PHP implementation target

• lib/BuiltinParamNames.php — rename quote_style → flags for both
• Reflection + named-arg dispatch; PHP-in-PHP only; no new C

Repro

./script/docker-exec.sh -- bash -lc 'php bin/vm.php -r '\''$r=new ReflectionFunction("htmlspecialchars_decode"); foreach($r->getParameters() as $p) echo $p->getName(), "\n"; try { echo htmlspecialchars_decode("&", flags: ENT_QUOTES), "\n"; } catch (Throwable $e) { echo $e->getMessage(), "\n"; }'\'''

Done when

• Reflection second param is flags (not quote_style) for both functions
• Zend-style named calls (string / flags / encoding) match Zend on VM
• Compliance .phpt + test/repro/issue_NNNN_*.php
• php-src-strict; no php-compiler-strict shortcut
