The change itself look correct for sure but can you tell me what it s fixing ? at first sight, the change seems pointless.

php_zip_parse_option is only called when options are passed to the function. Prior to this patch, php_zip_parse_option was responsible for zeroing the opts variable. So in the case when php_zip_parse_option is not called, opts remains uninitialized yet it is being used anyway.
By just always zeroing opts at declaration time, we avoid this issue and we are unlikely to reintroduce this in the future.

ah my bad, I did not unfold the full function :)

To be fair, I should've added that description in my commit/PR description itself. I've added it in the commit during merging.
