Is the name of the function something that could be reconsidered? I get that it's easy to type, but it is not descriptive at all. Something like dumpDie() would only be 5 more keystrokes (assuming no IDE with autocompletion is used), but would be a lot better in showing its intention.

Luckily, it looks like Php Inspections (EA Extended) will recognize this as a debug statement. Still, I think naming functions dd does not fit the Symfony philosophy.

Only in this case it's imo DX microoptimalization, that is worth it as you may write it thousand times a day...

I vote for dumpAndExitPhpSession personally. Much more descriptive. Seriously though, this is about developer convenience and happiness. It might not be descriptive at first, but once you know what is it, it makes a lot of sense and you'll save collectively many thousands of unnecessary keystrokes.

dumpd()? So it's easy to switch to die or not.

  1. This should never be committed => so other co-workers could not find it strange or not really descriptive
  2. In order to learn this new feature, you have to read the doc / blog post / this PR.

So basically, the name is not so important. So, IMHO, we should keep it small and simple

Looking at previous proposals, almost all of them proposed dd(). It feels like a strong indication this is the name we should settle for.

{
VarDumper::dump($var);

foreach ($moreVars as $var) {
VarDumper::dump($var);
}

exit(1);
}
}
