Does a file have to be writeable in order to be delete?

Hi,

Does a file have to be writable in order to be deleted?

If a file is writable using the php is_writable() function does it mean it can also be deleted because it is writable?

Reason for asking is before i attempt to delete a file and record from database i am checking if the file exists using file_exists() and then if file exists checking if it is then is_writable so i can delete the file using unlink();

But not sure if a file that is_writable is also able to be deleted.

Thanks

Yes, you need to have write permission for the file you want to delete, and according to a poster at the following link: "The folder that contains the file must ALSO have write permission."
