I have this problem too, with phpdocx 3.7 and php 5.6
Anybody can help us in this issue?
Hello,
It's due to how PHP 5.6 manages ZIP files when adding, replacing and removing content. PHP 5.6 was released after the launch of phpdocx 4, so this PHP version isn't official supported by phpdocx 3.
We recommend you to upgrade to phpdocx 5. The migration is easy and you just need to replace some methods by the new classes and methods. The new features worth the upgrading.
Regards.
