PHPStorm cannot use xdebug

[withinboredom]

This is probably on PHPStorm, but it fails to do remote step debugging because $_SERVER['SERVER_PORT'] is unset.

From looking at the code around https://github.com/dunglas/frankenphp/blob/main/cgi.go#L126, it looks like it should be set, but a simple var_dump($_SERVER) shows that it is indeed, not set.

I filed https://youtrack.jetbrains.com/issue/WI-71443 with them as well.

We should also fix it on our side, we can easily set this variable.

It works fine when it is truly remote (like running on a server). I only get this error when running on localhost or with a wildcard SERVER_NAME, like :80. Seems to be set properly when SERVER_NAME is an actual domain.

FWIW, in Caddy's fastcgi transport, we made a change to ensure a default of 80 or 443 is set for SERVER_PORT in caddyserver/caddy#4572 based on the incoming request's scheme. It looks like that code was copied from Caddy (identical comment) so I suggest it can be updated to match.

Yes it was. Maybe could we share it in some way btw.

We have caddyserver/caddy#4378 which is related to that, i.e. splitting out the fastcgi transport to its own package. If you'd like to help with that, that'd be cool.
