Regression: property hooks syntax accepted on default 8.2 profile — Zend parse error (re-#22371, Zend/zend_language_parser.y) #22781
Description
Category
Regression: · php-src-strict · profile gate (re-#22371 / re-#18531)
Problem
Default profile (Zend PHP 8.2.32 reference) must parse-error property hook syntax. As of master@0ae5abab2 (2026-07-24), bin/vm.php parses and executes hooks — same leak #22371 closed 2026-07-22.
| Repro | Zend 8.2.32 | VM (2026-07-24, default profile) |
|---|---|---|
public string $x { get => ...; set => ...; } |
Parse error: unexpected token "{" |
runs (a B) |
php-src reference
- php/php-src
Zend/zend_language_parser.y— property hook productions (PHP 8.4+) - Gate: only accept when
PHP_COMPILER_PROFILE≥ 8.4 (same bar as Language: property hooks syntax accepted on default 8.2 profile — must parse-error until PHP_COMPILER_PROFILE=8.4 (Zend/zend_language_parser.y) #18531)
PHP implementation target
- Parser / version gate in
lib/(language parser / profile checks) — reject hook property declarations on 8.2/8.3 profiles with a Zend-shaped Parse error (not a compile fatal) - Do not add C runtime branches
Repro
./script/docker-exec.sh -- bash -lc 'cat > /tmp/hooks_profile.php <<\"PHP\"
<?php
class T {
private string $_x = \"a\";
public string $x {
get => $this->_x;
set => $this->_x = strtoupper($value);
}
}
$t = new T;
echo $t->x, \" \";
$t->x = \"b\";
echo $t->x, PHP_EOL;
PHP
php /tmp/hooks_profile.php; echo EXIT_ZEND:$?
php bin/vm.php /tmp/hooks_profile.php; echo EXIT_VM:$?'Done when
- Default profile: VM emits Zend-shaped parse error (non-zero); snippet does not run
-
PHP_COMPILER_PROFILE=8.4: same snippet still works (a B) - Compliance/

Maintainer re-check (0ae5aba)
Repro from the issue body is not reproducible on current
master@0ae5abab2— VM already matches Zend 8.2 rejection:Parse error: unexpected token \"{\"syntax error, unexpected identifier \"X\", expecting \"=\"new T()->m()Parse error: unexpected token \"->\"public private(set)Fatal error: Multiple access type modifiers are not allowedClosing as already fixed / stale observation. Fresh PROFILE=8.3/8.4 gate gaps filed as #22792–#22795.

Closed: default-profile Zend rejection already matches on master@0ae5abab2 (see prior comment).
