We are using soap client library in our application to fetch Salesforce
data using API in PHP.
When we run simple php page it runs properly but not with soap client.
We run this command and getting error as shown below
$ heroku run php www/sandbox/index-test.php
Running `php www/sandbox/index-test.php` attached to terminal... up, run.1586
