php-in-php: VmLocaleCollate — host strcoll/strxfrm, drop libc FFI (#1492) #13566
Description
Category
php-in-php · php-src-strict
Problem
VmLocaleCollate uses libc strcoll(3) / strxfrm(3) via ext/ffi. Under Zend bootstrap, host \strcoll() / \strxfrm() provide the same semantics without FFI.
php-src reference
- ext/standard/string.c — PHP_FUNCTION(strcoll), PHP_FUNCTION(strxfrm)
Scope
| Path | Work |
|---|---|
ext/standard/VmLocaleCollate.php |
Prefer host builtins; strcmp/identity fallback for self-host |
| Tests | test/unit/VmLocaleCollateRuntimeShrinkTest.php |
Done when
- No
\FFIin VmLocaleCollate.php - strcoll/strxfrm VM matches Zend on repro

Merged via #13567.
Verification: VmLocaleCollateRuntimeShrinkTest 3/3 (6 assertions); bootstrap VM driver probe OK.
Shrink: removed libc strcoll/strxfrm FFI from VmLocaleCollate.php (−47 lines FFI logic).
