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.
(PHP 5 >= 5.3.2, PHP 7, PHP 8)

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';
?>
```
