The SMS Validation service allows the validation of physical phone number to be used as the sender of an SMS.
First, call setValidationKeyword() to receive an SMS
with a keyword.
After you get your keyword, you have to use the validate() to
validate your number with the keyword against the service.
With the method getValidatedNumbers(), you will get a list
of all already validated numbers and the status of each.
Example 788. Request validation keyword
<?php
$service = new Zend_Service_DeveloperGarden_SmsValidation($config);
print_r($service->sendValidationKeyword('+49-172-123456'));
Example 789. Validate a number with a keyword
<?php
$service = new Zend_Service_DeveloperGarden_SmsValidation($config);
print_r($service->validate('TheKeyWord', '+49-172-123456'));
To invalidate a validated number, call the method inValidate().
