Php 在codeigniter中使用facebook sdk的基本要求

我想知道基本要求，比如

• 编码点火器版本
• php版本
• facebook的php sdk版本

我在用PHP5.3.5和codeigniter 2.2尝试facebook sdk版本3。行吗？

请引导我。

我确信它能起作用。建议您实际开始构建它，如果它不起作用，请在stackoverflow中发布错误，我相信社区会提供帮助。

步骤1：下载和设置文件夹

我会尽量让这句话简短甜蜜：

Download the Facebook SDK for PHP from GitHub

步骤2：创建和定义配置变量

您还需要设置一些配置变量。在application/config/config.php或您自己的配置文件（我建议您这样做）中创建以下变量：

<?php
$config['facebook']['api_id'] = 'YOUR APP ID';
$config['facebook']['app_secret'] = 'YOUR APP SECRET';
$config['facebook']['redirect_url'] = 'http://www.yourwebsite.com/login';
$config['facebook']['permissions'] = array(
'email',
'user_location',
'user_birthday'
);

例如，如果您希望获取登录URL（用户授予访问权限的位置）：

打印（用户档案）

只有一种方法可以找到答案@伊斯温基是吗？如何找到它？对于投票否决这个问题的人，我没有得到关于它的信息，所以我在这里问了它。如果你对某件事知之甚少，那不是犯罪。谢谢，我会试试看。

<?php
$config['facebook']['api_id'] = 'YOUR APP ID';
$config['facebook']['app_secret'] = 'YOUR APP SECRET';
$config['facebook']['redirect_url'] = 'http://www.yourwebsite.com/login';
$config['facebook']['permissions'] = array(
'email',
'user_location',
'user_birthday'
);
