virtualmin install php-soap for wordpress

I followed some of the discussion to install the php-soap and I got the following result on CentOS-7

PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib64/php/modules/php_soap.dll’ - /usr/lib64/php/modules/php_soap.dll: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: Unknown: It is not safe to rely on the system’s timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone ‘UTC’ for now, but please set date.timezone to select your timezone. in Unknown on line 0
Soap Client => enabled

soap.wsdl_cache_enabled => 1 => 1
soap.wsdl_cache_limit => 5 => 5

How can I solve the problem?
