What problem exactly are you trying to solve, and do you have a way of
showing the problem that isn't just what looks like a programming
mistake?
e.g. The following code works fine. The file being closed doesn't
affect the filehandle
$fileHandle = fopen('foo.txt', 'r+');
unlink('foo.txt');
$data = fread($fileHandle, 20);
The following code doesn't work fine. The filehandle being closed,
surprisingly enough, makes it not usable any more:
$fileHandle = fopen('foo.txt', 'r+');
fclose($fileHandle);
$data = fread($fileHandle, 20);
or, as the link you sent puts it:

So I don't understand what problem you're trying to analyze, other
than closed file descriptors are closed.
