Question

I am trying to use Google-API-PHP-Client and its base class is throwing following error:

Severity: Warning

Message: array_merge() [function.array-merge]: Argument #1 is not an array

Filename: libraries/Google_Client.php

Line Number: 107

Code around like 107 is something like:

public function __construct($config = array()) {
    global $apiConfig;
    $apiConfig = array_merge($apiConfig, $config);
    self::$cache = new $apiConfig['cacheClass']();
    self::$auth = new $apiConfig['authClass']();
    self::$io = new $apiConfig['ioClass']();
  }

I understand that global $apiConfig is not initialized as array that’s why array_merge is throwing error. But when I change it to global $apiConfig = array();, got another error Parse error: syntax error, unexpected '=', expecting ',' or ';' in C:\Softwares\xampp\htdocs\testsaav\application\libraries\Google_Client.php on line 106

I am using Codeigniter 2.3 with XAMPP which has PHP 5.3

Answer 1

Initialize your array in your function (if necessary)

public function __construct($config = array()) {
    global $apiConfig;
    $apiConfig = (isset($apiConfig) && is_array($apiConfig)) ? $apiConfig : array(); // initialize if necessary
    $apiConfig = array_merge($apiConfig, $config);
    self::$cache = new $apiConfig['cacheClass']();
    self::$auth = new $apiConfig['authClass']();
    self::$io = new $apiConfig['ioClass']();
  }
