Call to unknown function (PHP0417)

SteveA

Several function calls in a project I am working on report "Call to unknown function" with the warning code PHP0417, however the code runs fine and I can step into the functions from the debugger (Visual Studio 2019 version 16.11.8 and PHP Tools 1.59.15092).

Noteworthy, the "unknown" functions are in nested include files similar to:

main.php has require("include_1.php") which has require("include_2.php") which has require("include_3.php"). The include_3.php file contains the "unknown" function.

Yeah, it looks rather crazy as I post this, but this series of include files is a fairly clean method we use to share functions across 12+ projects (it's sort-of a pseudo library).

Thanks!

Hi, thank you for reporting the issue;

require actually does not matter. IntelliSense and "unknown" errors look at all the files in the project, so once the file with those functions is included in the project, it shouldn't be underlined.

So just to confirm; are all the files included in the project?

All files were "included" via the "require()" statement, however not all files were marked as "Include in Project" in the Solution Explorer. Selecting that resolved the problem. Thanks.

great! thanks for the feedback and for letting us know.

The way PHP Editors work is, they parse the entire project workspace, not following the require/include within the code since it's not complete definite.

Since Visual Studio 2019, every newly created PHP project automatically contains the entire project folder which avoids similar problems.

Thanks,
Jakub
