I'm generally not in favour of new ini settings. I also don't think this is going to help a lot, as many people will likely not change the default. But, I am especially not keen on "negative names". Names that include "ignore" or "disable" for example. If you must have an ini setting, it ought to be something like "include_error_args" (defaulting to "0", I suspect). The confusion in https://github.com/php/php-src/pull/12276#pullrequestreview-4035216287 also explains why I feel this. cheers, Derick -- https://derickrethans.nl | https://xdebug.org | https://dram.io Author of Xdebug.
