Twig 快速集成

假设你的项目项目使用composer

1. 安装，为了兼容php5.4使用的是1.x版本

composer require twig/twig:~1.0

2. 封装为trait以集成

namespace objects\Traits;

trait DoufuTwig {

    /**
     * @var \Twig_Environment
     */
    private $twig;

    protected function renderTwig($path, $data = []) {
        if (! $this->twig) {
            $loader = new \Twig_Loader_Filesystem(APPPATH . 'views');
            $this->twig = new \Twig_Environment($loader, 
                array(
                    'cache' => APPPATH . 'cache',
                    'auto_reload' => true
                ));
        }
        
        return $this->twig->render($path, $data);
    }
}

3. 使用

集成到控制器父类

namespace Ncontrollers;

use objects\Traits\DoufuTwig;

abstract class Controller
{
    use DoufuTwig;
}

控制器内使用

...
echo $this->renderTwig('xxx/login.html');
...

Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set ‘always_populate_raw_post_data’ to ‘-1’ in php.ini and use the php://input stream instead.

edit php.ini and set always_populate_raw_post_data = -1

; Always populate the $HTTP_RAW_POST_DATA variable. PHP’s default behavior is
; to disable this feature and it will be removed in a future version.
; If post reading is disabled through enable_post_data_reading,
; $HTTP_RAW_POST_DATA is *NOT* populated.

always_populate_raw_post_data = -1

奇异的setcookie无效问题

api.xxxx.com/aaa 页面下setcookie，

api.xxxx.com/xxx，cookie 有效

api.xxxx.com/index.php/xxx，cookie 无效

其实是cookie path的问题

setcookie($key, $value, null, ‘/’, null, null);
