opcache.enable=1
opcache.memory_consumption=256          ; MB — increase for large codebases
opcache.interned_strings_buffer=16      ; MB — reduces string duplication
opcache.max_accelerated_files=20000     ; rounded to next prime internally
opcache.validate_timestamps=0           ; DISABLE in production — requires manual reset on deploy
opcache.save_comments=1                 ; required by Doctrine, PHPUnit, many frameworks
opcache.optimization_level=0x7FFEBFFF   ; all safe optimizations (default)
