I try to lookup the declaration of File but PhpStorm says Cannot find declaration to go to.
I also tried it with netbeans, it can't find the declartion too. I also tried to lookup the alias use File;
I get No usage found in project files.
How does my code even know what it has to do if It can't find any declarations? This makes no sense to me.
How can I find out where File is declared?
