Installed soap version:
Output of following command :
yum search php-soap
php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
Also,
yum search php | grep -i soap
Returns
php-pear-SOAP.noarch : Simple Object Access Protocol (SOAP) Client/Server for
php-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php56u-soap.x86_64 : A module for PHP applications that use the SOAP protocol
php-ZendFramework-Soap.noarch : SOAP web services server part helper
php-ZendFramework2-Soap.noarch : Zend Framework 2: SOAP Component
Under module authors, It shows SOAP Brad Lafountain, Shane Caraveo, Dmitry Stogov. But my phpinfo() call does not show the SOAP section.
PHP Version 5.6.5
yum install php56u-soap
worked for me.
