Issue with accessing property in Google_Service_Exception - php

Question

I'm following a tutorial on how to use the Google Reseller API. I've come to the section on determining whether a customer already exists in Google Apps (Step 2) but have come unstuck in handling the Google_Service_Exception object.
If a customer doesn't exist then a call to the API will return a 404 error. I'm using the code property of the Google_Service_Exception object $e to determine if the response has a 404 error. However when I try to return the error code with $e->code with:
try {
// Call to the Google Reseller API
} catch (Google_Service_Exception $e) {
if($e->code == 404){
return false;
}
}
I get the following PHP error:
Fatal error: Cannot access protected property Google_Service_Exception::$code.
The Google_Service_Exception class is as follows:
<?php
require_once 'Google/Exception.php';
class Google_Service_Exception extends Google_Exception
{
/**
* Optional list of errors returned in a JSON body of an HTTP error response.
*/
protected $errors = array();
/**
* Override default constructor to add ability to set $errors.
*
* #param string $message
* #param int $code
* #param Exception|null $previous
* #param [{string, string}] errors List of errors returned in an HTTP
* response. Defaults to [].
*/
public function __construct(
$message,
$code = 0,
Exception $previous = null,
$errors = array()
) {
if (version_compare(PHP_VERSION, '5.3.0') >= 0) {
parent::__construct($message, $code, $previous);
} else {
parent::__construct($message, $code);
}
$this->errors = $errors;
}
/**
* An example of the possible errors returned.
*
* {
* "domain": "global",
* "reason": "authError",
* "message": "Invalid Credentials",
* "locationType": "header",
* "location": "Authorization",
* }
*
* #return [{string, string}] List of errors return in an HTTP response or [].
*/
public function getErrors()
{
return $this->errors;
}
}
So I assumed the error has something to do with the fact that $errors is protected. I imagine it is protected for a reason so I was a bit wary of changing the class. Any help / pointers in working around this error would be greatly appreciated. Thanks

Answer 1

Just use the getCode() method:
try {
// Call to the Google Reseller API
} catch (Google_Service_Exception $e) {
if($e->getCode() == 404){ // <- Change is here
return false;
}
}
Google_Service_Exception extends Google_Exception and Google_Exception extends Exception. You may read the documentation about Exception here. You will see the getCode method.
