Regression: parse_ini_file() missing path — returns NULL not false (ext/standard/ini.c) #13475
Description
Category
stdlib · php-src-strict
Problem
parse_ini_file() on a non-existent path returns NULL on VM. Zend returns false (and emits E_WARNING).
Sibling stat()/lstat()/filemtime() NULL-vs-false regressions are tracked separately (#13459, #13460, #10302); parse_ini_file() is not covered by those issues.
