yii?rules()

<br />public function rules()<br />	{<br />		return array(<br />			array('display, title', 'required'),<br />			array('title', 'length', 'max'=>300),<br />            array('id, display, date, title', 'safe'),---(1)<br />			array('id, display, date, title', 'safe', 'on'=>'search'),---(2)<br />		);<br />	}<br />

(1)和(2)的作用是什么?

看看文档吧，说不清楚...
------解决思路----------------------
safe 安全的

array('id, display, date, title', 'safe')
表示 id, display, date, title 可安全的使用，即不需要检验

array('id, display, date, title', 'safe', 'on'=>'search')
中的 'on'=>'search' 表示本条规则适用于 search 模块

其实这个思维方法与我们的有很大的不同
他先假定所有的传入数据都需要验证，然后在规则中开列可以跳过验证的字段

而我们一般这样做：假定所有传入的数据都是安全的，然后开列出需要检查的字段

How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AM
