### Example of trimming a number and substituting 8 at the beginning

* 4991234567 will be replaced with 84991234567 
* 1234567 will be unchanged 
* 39974991234567 will be replaced with 84991234567 
* 74991234567 will be replaced with 84991234567 
* +74991234567 will be replaced with 84991234567

```
$phone = $params['phone'];

// Getting the last 10 digits of the number
if(preg_match('/([0-9]{10})$/', $phone, $match)){
// if the number has 10 digits at the end, then add an eight to the beginning
    $phone = '8' . $match[1];
}

return array(
    'state' => 'success',
    'data' => array(
        'phone' => $phone,
    ),
);
