Changelog
| Version | Description |
|---|---|
| 7.3.0 | On Windows, it is now possible to unlink() files with handles in use, while formerly that would fail. However, it is still not possible to re-create the unlinked file, until all handles to it have been closed. |
Examples
Example #1 Basic unlink() usage

$fh = fopen('test.html', 'a');
