Class not found with Php app hosted on Heroku

Question

I developp a PHP application hosted on Heroku and which use the PHP Toolkit to interact with Force.com.

When I run the app on my computer, it works, data from Salesforce.com are loaded but when I push my app on the Heroku server, I get this error :

Class 'SoapClient' not found in /app/Soapclient/SfocePartnerClient.php on line 44

Line 44 :

class SforceSoapClient extends SoapClient {
  ...
}

What have I to configure on Heroku to fix the error please?

Answer 1

I fixed it by requiring "ext-soap" in composer.json:

{
    "require": {
        "ext-soap": "*",
        "php": ">=5.4.0"
    }
}

Run composer update to generate a composer.lock file, and push both files to Heroku, or manually deploy from Dropbox via https://dashboard.heroku.com/apps/your-app-name/deploy/dropbox

Answer 2

It didn't work because the soap extension wasn't correctly activated.

I had to create a case to the Heroku support.

Now, it works fine.
