>PHP enables this type of underestimation in your own abilities. You don't need to distrust yourself so much. That might be true, but sometimes it happens that you overestimated and introduced a breaking change 20 changes ago and now you have to rewind your steps back to find the exact place. If an iteration can be done in less than a second, it's probably cheaper (and less stressing) to just check every single change like this. This is what many coding editor integrations actually do for you.
