Question

PHP

Hello. You need to post messages in a Facebook group. In order to post messages, you need extensions that are issued based on the finished application, after it has been tested. I can’t write an application without checking, 100% I’ll screw up somewhere. is there any option in which I can check for myself how what I write works?
