    stream_resolve_include_path() seems to cache it's output. After I renamed a file, I had to restart Apache for stream_resolve_include_path() to not return non-existing file name. This was on Windows.

    In some case like this, you can't use `realpath()` or `file_exists()` without resolve its path.Example:file.phpsubfolder/..|- included.php..|- subfolder/.........|- another-included.phpfile.php contents:```<?phpvar_dump(file_exists('subfolder/included.php'));// trueinclude 'subfolder/included.php';?>```subfolder/included.php contents:```<?phpvar_dump(file_exists('subfolder/another-included.php'));// false but the file is really exists.var_dump(file_exists(stream_resolve_include_path('subfolder/another-included.php')));// with `stream_resolve_include_path()` function, it returns true now.include 'subfolder/another-included.php';// working fine, no errors.?>```subfolder/subfolder/another-included.php contents:```<?phpecho 'Hello world';?>```
