Description:
------------
file_put_contents() blocks the directory of the file (__DIR__)

This is PHP 7.3 beta and RC regression.
There is no problem with PHP 7.2.x.

1. Create file using file_put_contents()
2. Now, you can NOT remove the directory of the file (__DIR__).

It happens only when FastCGI using.

Test script:
---------------
<?php
// Windows 10 Pro 1803
// PHP 7.3RC2 NTS 64 bit
// Only FastCGI problem
// BUG: file_put_contents() blocks the directory of the file (__DIR__)

 file_put_contents('temp.txt','');

// Now, try to remove manualy the directory of the file (__DIR__ with content)
// PHP 7.3.RC2 - you can not!
// PHP 7.2.10 - you can
?>

Expected result:
----------------
I can remove the directory of the file (__DIR__).

Actual result:
--------------
I can NOT remove the directory of the file (__DIR__).

You say regression. Was this reported as a bug and fixed in the past?

Are you sure the problem is not that you have PHP running as a different user, and the created file has ownership/permissions set that you cannot remove it and thus cannot delete its parent directory?

File can be deleted. Only directory is blocked.

File can be deleted.
Only directory is blocked until you stop PHP service.
