首先我是用过codeigniter的，刚开始学框架的时候用过一阵子，然后后来公司用thinkphp，就没再用了，用了2个之后，就会有一些对比性。首先这2个框架文件夹容量都比较大，称不上轻量级之类的，我都不怎么看好。
今天单说codeigniter框架
举个官网控制器调用模板的例子
<?phpclass Blog extends CI_Controller { function index() { $data['title'] = "My Real Title"; $data['heading'] = "My Real Heading"; $this->load->view('blogview', $data); }}?> <html><head><title><?php echo $title;?></title></head><body> <h1><?php echo $heading;?></h1></body></html>

十年了！！！
就因为今天第 四月一号 吗？
LZ推荐几个框架呗！~

你怎么看

没什么推荐呀~我就用过那2个，缺乏全面的对比性。

codeigniter 不是模板引擎
既然是框架，当然他也有自己的模板引擎
10年前的东西，过于陈旧了
你不也想着标新立异吗？

你怎么看
你这个template与ci的有什么不同？
模板说到底，还不是ob＋extract？
php amp
你怎么看
推荐ci，是ci容易上手，模板，不都是差不多么，
其实框架没有对错,看需求.比如我现在公司项目紧急,来的都是新人,能力参差不齐.CI框架就很适合,有框架使用经验的,用这玩意1,2天基本就能上手开发.
不过,局限性也很明显 ...
我个人认为CI还是蛮好的，mvc分工明细，代码简单清晰明了
CI还可以吧，我一直在用也没发现有什么问题。
php amp
你怎么看
public function renderPhpFile($_file_, $_params_ = []) { ob_start(); ob_implicit_flush(false); extract($_params_, EXTR_OVERWRITE); require($_file_); return ob_get_clean(); }
