  • Component changed from General to Filesystem API
  • Focuses docs removed
  • Keywords 2nd-opinion added
  • Priority changed from normal to low

A missing break statement does not automatically indicate an error in the code. An expression can match multiple case conditions and intentionally fall through (this happens in the large switch statement in the map_meta_cap() function).

In this case, it does look like the break statement is missing, but I don't believe there is a reason to "fix" this unless a bug can be identified.

This looks to be intentional to me.

PCLZIP_OPT_BY_EREG is deprecated, so it overwrites PCLZIP_OPT_BY_EREG with PCLZIP_OPT_BY_PREG in the args array, and then performs the validation for the parameters for ..PREG which is what now happens when you use ..EREG

Code in question with more context:

It's also worth noting, that PclZip is not a WordPress library, it's home is over at http://www.phpconcept.net/pclzip and bugs in it can be reported directly to the author. Over the years we've made some updates to the library for PHP compatibility, but that's it.

Unless this is causing a PHP Warning or related message or an actual bug, I'm marking this as invalid. A warning from a code sniffer or similar tool isn't enough of a reason to change it IMHO.

@dd32 Thanks for providing information for that. I take care next time about PHP warning.

@johnbillion @dd32 Should an // Intentionally falling through to next case. comment be added maybe to make it indisputable that this in the intended behaviour ? /cc @DrewAPicture
