最近发现在class 中给私有变量赋值的时候调用了函数就会报错,不得其解释,OOP方面的菜鸟,请高手解释?
class Test extends Controller { //测试 private $test = count('csdn');}
Parse error: syntax error, unexpected '(', expecting ',' or ';'
回复讨论(解决方案)
测试写错了,是字符串长度
class Test extends Controller { //测试 private $test = strlen('csdn');}

这并非是私有属性的原因
而是类属性在声明时不能赋予不确定的值!
define('TEST', strlen('csdn'));class Test extends Controller { //测试 private $test = TEST;}这样写是可以的
多谢,多谢

受教了
define('TEST', strlen('csdn'));class Test extends Controller { //测试 private $test = TEST;}这样写是可以的

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
