In practice, this only works for detecting syntax errors, because (1) a script does not usually survive isolated, (2) it's unfeasible to bootstrap an entire application like this, (3) it does not create a testing/repeatable context, (4) not having all the context set up could cause false fatal errors like undefined function. Thus, instead of executing php $tempfile it's better to execute php --no-php-ini --syntax-check $tempfile. php.net/manual/en/features.commandline.options.php

Can you prove that? I don't think so

Well, it "works" in the console because I see the fatal error. The $return is always 255 for the six uncatchable errors and always 0 otherwise. I think I need a shutdown handler to get to the error code. -- as for PHPUnit, even if I @runInSeparateProcess a single test causing a fatal error, it always appears as an 'E'. -- Your idea is interesting, and I upped you before. But to make it work, I think I need to dig into PHPUnit and write a patch or plugin. I wonder why nobody did it before. Is it unreasonable to expect a script to fail?

Now I got your concerns. Will play around with PHPUnit a little bit, probably write some code and give you a feedback..

I've found there is a customizable isolation template. There we need to register_shutdown_function('__phpunit_shutdown', $test, $result). __phpunit_shutdown($test, $result) (in case of error) only prints a serialized array like usual, but with an added error key set to error_get_last(). Then we can add support for an @expectedShutdownError <code> from PHPUnit_Util_PHP::runTestJob, which would call processChildResult with doctored arguments (mainly stderr = '').
