Ah, fine. How do i use this ZIPARCHIVE::CHECKCONS flag?
Something like that should work, i think?
$zip = new ZipArchive;
$res = $zip->open ( $filename ZIPARCHIVE::CHECKCONS );
if (TRUE === $res) {
# all looks fine
}
else {
switch($res){
case ZIPARCHIVE::ER_INCONS:
# do some error handeling
break;
}
# test these errors
# ZIPARCHIVE::ER_EXISTS
# ZIPARCHIVE::ER_INCONS
# ZIPARCHIVE::ER_INVAL
# ZIPARCHIVE::ER_MEMORY
# ZIPARCHIVE::ER_NOENT
# ZIPARCHIVE::ER_NOZIP
# ZIPARCHIVE::ER_OPEN
# ZIPARCHIVE::ER_READ
# ZIPARCHIVE::ER_SEEK
}

Perhaps checking the consistency with this ZIPARCHIVE::CHECKCONS flag
would help.
This is just a wild guess.
