unlink

(PHP 4, PHP 5, PHP 7, PHP 8)

unlink — Deletes a file

unlink(string $filename, ?resource $context = null): bool

Deletes filename. Similar to the Unix C unlink() function. An E_WARNING level error will be generated on failure.

filename

If the file is a symlink, the symlink will be deleted. On Windows, to delete a symlink to a directory, rmdir() has to be used instead.

context

resource контекст потоку.

Повертає true у разі успіху або false в разі помилки.

Версія	Опис
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.

Приклад #1 Basic unlink() usage
