php-ews: Class 'SoapClient' not found when using full path to the Classes

Question

Implementing php-ews on the existing non-OOP website.

Running standalone PHP script in shell works fine.

Standalone PHP script uses use:

use \jamesiarmes\PhpEws\Client;
use \jamesiarmes\PhpEws\Request\CreateItemType;

But I can't use use inside if-statements on the website, so I prepended all Classes using full path (i.e. new \jamesiarmes\PhpEws\Client).

Now I'm getting this error.

Fatal error: Class 'SoapClient' not found in /home/project/master/vendor/jamesiarmes/php-ntlm/src/SoapClient.php on line 13

I verified that Soap extension is installed. Please help. Thanks.

Running standalone PHP script in shell works fine.

but

I verified that Soap extension is installed.

How have you verified? You know you may be loading different php.ini files for CLI and Webserver environments.

(For example, in my Ubuntu server, with Apache webserver, I have both

/etc/php5/cli/php.ini

and

/etc/php5/apache2/php.ini )
