first of all I explain the reason why I try to do it. I tried many editors/IDEs which could provide convenient syntax and variables check. Eclipse did the best.
But it works correctly only if I work with its project, otherwise there are a lot of glitches and no correct support of syntax suggestion/auto-complete.
I set my FTP client to download files into project's folder, but Eclipse does not recognize them as a part of this project so I still don't have it's full support. If I create PHP files with Eclipse in the same folder it works just fine. Is there a way to make read all PHP files in project folder as parts of a project?
Or, if you can suggest IDE which performs syntax check/auto-complete tasks as Eclipse does please do, I check if I tried it. I can't include all CMS into project, because it is Bitrix, it can kill any IDE which can try to chew it, so I just need a reliable tool which could work as code validation of currently edited script. The perfect tool could just be set for PHP 5.6/7.1 for example and perform validation based on language rules.
