ThinkPHP学习(五)图片验证码

今天用到图片验证码的功能,在网上找到ThinkPHP的以下代码:

	Public function verify(){		import('think.Image');		Image::buildImageVerify();	 }
添加到Controller中,通过地址“http://localhost/index.php/passport/index/verify”来访问,却提示以下错误:

Class 'Passport\Controller\Image' not found


我的ThinkPHP版本是:3.2.1,经过查看对应版本的文档“http://document.thinkphp.cn/manual_3_2.html#verify”,发现需要使用以下代码:

	Public function verify(){		$Verify = new \Think\Verify();		$Verify->entry();	 }
但刷新浏览之后又出错了“Call to undefined function Think\imagecreate()”


搜索之后发现是没有启用“extension=php_gd2.dll”扩展,在php.ini中去掉前边的分号; 再刷新浏览图片验证码就出来了。
