Can I See *How* a function is known to PHPStorm?
I am calling a function in a PHP script. I have a require_once statement at the top which references the file which contains the function. In the editor, PHP displays the function call normally, since it knows where it's located.
If I comment out the require_once statement, PHPStorm still seems to know about where the function is, even though I think it shouldn't. Is there a way for me to see *how* PHPStorm knows about the function, given that I've commented out the line that includes it? I'm concerned that another file is including it that I'm not aware of.
Thanks,

It's actually pretty simple - PhpStorm doesn't care about include/require statements or autoloading, it analyzes all files in the project, and if in the given namespace, there is a variable/function/class/whatever with the given name - it makes a reference.
If there's more than one symbol with the same name defined in different files, you'll get the multiple definition inspection hit.
Okay, so if I understand you correctly, the editor will not show a function call as "unknown" if I comment out the require_once statement. It will fail on the server but it's not something that PHPStorm will catch in the editor. Seems like this is something they could check for.
You are right, but it's an approach we intentionally dismissed because people mostly go with autoloading: https://youtrack.jetbrains.com/issue/WI-1480#focus=streamItem-27-2114274.0-0
