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.

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);

stuck key XX

今天维修公司笔记本，开机显示

stuck key XX

上网查询到是键盘某个键处于按下状态，无法弹起

XX就是坏掉的键的编码

PHP Fatal error: Can’t use function return value in write context

empty

(PHP 4, PHP 5, PHP 7)
empty — 检查一个变量是否为空

说明 ¶

bool empty ( mixed $var )
判断一个变量是否被认为是空的。当一个变量并不存在，或者它的值等同于FALSE，那么它会被认为不存在。如果变量不存在的话，empty()并不会产生警告。

Note:
在 PHP 5.5 之前，empty() 仅支持变量；任何其他东西将会导致一个解析错误。换言之，下列代码不会生效： empty(trim($name))。 作为替代，应该使用trim($name) == false.

    // Create Router instance
    $router = new \Bramus\Router\Router();
    
    # loader
    include APPPATH . 'hooks/doufu_autoload.php';
    $_doufu_loader_ = new doufu_autoload();
    $_doufu_loader_->run();
    
    // Define routes
