   This function is available only in CLI mode.

   It is referring to the PHP official cli-sapi, which FrankenPHP (apparently) does not fully implement, and I'm not sure that it should, IMHO, since it does many slightly interesting things, such as setting different constants for i/o streams, how the working directory is applied, etc.

   Laravel probably shouldn't blindly call a function only available in a specific SAPI without checking that it exists first, but FrankenPHP also probably shouldn't impersonate the official CLI SAPI.

   @dunglas, how do you feel one way or the other?

   Copy/pasting this function in FrankenPHP should do the trick.

   Copy/pasting the C implementation of this function coming from the official PHP CLI SAPI.

   So is there we can do in the userland? or is it done on the library side?

   This should be done in frankenphp.c in this repo.

   I'm concentrating on hunting down the remaining bugs, but then I'll work on this if no one else does it first!
