    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.php
    subfolder/
    ..|- included.php
    ..|- subfolder/
    .........|- another-included.php

    file.php contents:
    ```
    <?php
    var_dump    (file_exists('subfolder/included.php'));// true
    include 'subfolder/included.php';
    ?>
    ```

    subfolder/included.php contents:
    ```
    <?php
    var_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:
    ```
    <?php
    echo 'Hello world';
    ?>
    ```
