Unabled to format PHP on self hosted Cloud9 about c9.ide.format HOT 1 OPEN

Excuse me for using DeepL Translate.

I had the same problem, but I found a way to make it work on my self-hosted Cloud9!

The solution is to start Cloud9 in co-editable mode with "--collab" in the startup options, and then run the following bookmarklet to have the co-edit user ID registered in the cookie, so that php-cs-fixer will automatically run on save.
If "Share" is displayed in the upper right corner of the screen, you have succeeded.
You may need to reload the editor screen after registering the cookie.

javascript:(function(){javascript:document.cookie='__c9_uid='+escape(JSON.stringify({id:1}))+';Domain=.com;Max-Age=315360000'})()

In the new Edge, the bookmarklet doesn't seem to run from the address bar, so try running it from the Developer Tools console.

I hope this helps.
