CLI Web Server customization

Hello everyone. Currently, I am working on a project that allows PHP applications to be developed with a GUI frontend based on Chromium - and later on CEF. For this to work properly, I am spawning a new Chromium process with some command line switches to allow customization of the launch. This means, I can pass in the URL which should be opened, and disable features such as translation and alike. However, the problem is the HTTP backend. Currently, I am using a PHP script in the same process as the "watching" process - which is basically a while loop that awaits for a client connection. By using the pthreads extension, I am also handling events that are received by the Remote Debug Protocol via a WebSocket connection (PHP acting as a client here). As you can see, this is a little chaos. So I have the event listener, the Webserver and process watcher for Chromium in seperated threads. Once the browser is quit, I have to use posix_kill to make sure the webserver dies as well - because it simply wouldn't. So I got to the conclusion that I may change the logic, and remove the webserver, and replace it by another spawned process of the PHP CLI HTTP server. The problem is, I'd want to customize it some. Like, customize error pages, logging, etc. I am also curios about something else. Back in some time, the PHP manual read that the HTTP server is "for development only". The problem is, I do not want to package an apache webserver into the bundle - or do some nodejs scripting for some webserver. I'd like to stay on a PHP basis. Would be great if you can explain some things to me here!
