Answer 1

PHP 7 throws a ParseError exception instead of triggering an error of type E_PARSE. The default exception handler seems to trigger an error if an uncaught exception is encountered. However if you replace it with set_exception_handler() it no longer happens unless you do it yourself.

See PHP docs:

PHP 7 changes how most errors are reported by PHP. Instead of reporting errors through the traditional error reporting mechanism used by PHP 5, most errors are now reported by throwing Error exceptions.
