On both a CentOS 6.8 and CentOS 7.2-1511 system a yum update gives this warning

Updating   : php-pecl-zip-1.13.5-1.el6.remi.5.6.x86_64                   2/22
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/curl.so' - /usr/lib64/php/modules/curl.so: undefined symbol: zend_unset_property in Unknown on line 0

The same warning occurs when updating php-pecl-zip-1.13.5-1.el7.remi.5.6.x86_64 on CentOS 7.2-1511. I worked around the issue by not updating to the php-pecl-zip-1.13.5-1.el6.remi.5.6.x86_64 (CentOS 6.8) or php-pecl-zip-1.13.5-1.el7.remi.5.6.x86_64 (CentOS 7.2-1511) by this command:

> yum --exclude=php-pecl-zip update

I am not sure where to get the missing symbol or would have fixed that. I am hoping somebody might be able to tell me what I am missing on my systems. Thanks.
