很好理解啊。
比如一个函数中你注册了两个回调,示例代码:
function somefunc1(){ //some code... //Throw a exception throw new \Exception('I am a exception!'); } function somefunc2(){ //some code... //Not throw a exception }
恰好,在你执行的时候, somefunc1()
的异常被抛出来了,这时候,在你的要使用的回调函数的函数中,你必须:
try { call_user_func('somefunc1'); } catch (\Exception $e) { echo $e->getMessage(); } //以下函数在异常时候会继续执行 call_user_func('somefunc2');
如果你没有像上述那样子去捕获异常,代码示例如下:
call_user_func('somefunc1'); //当异常抛出的时候,一下代码不会继续执行 call_user_func('somefunc2');
以上。

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
