Codice PHP:
file_put_contents(__DIR__.'/.user.ini', ''); 
file_put_contents(__DIR__.'/php.ini', ''); 
putenv('PHP_INI_SCAN_DIR='.__DIR__); 
echo 'PHP_INI_SCAN_DIR: '.getenv('PHP_INI_SCAN_DIR')."\n"; 
echo "php_ini_loaded_file():\n".php_ini_loaded_file()."\n"; 
echo "php_ini_scanned_files():\n".php_ini_scanned_files()."\n"; 
Output:

Sembra che i file __DIR__.'/.user.ini' e __DIR__.'/php.ini' vengano completamente ignorati.
Perchè?

Forse non ho capito bene il funzionamento
