为什么WAMP里PHP开户了display errors后不能创建图片
请问？
为什么WAMP里PHP开户了display errors后不能创建图片，以至于不能创建验证码。
关掉display errors后，又能创建图片了。
------解决方案--------------------
每次用全局变量，都用isset检测一下。
比如$sess=isset($_SESSION['mysession'])?$_SESSION['mysession']:"";
对于图片，还要检测是否有BOM。

May 15, 2023 pm 02:37 PM
The problem was found in the springboot project production session-out timeout.

Unlike the ProDisplayXDR, the StudioDisplay has a unique power connector that appears to be non-removable. It turns out that the cable is removable, but you'll need a special tool to remove it. Apple says on its website that the Studio Display's power cord is not detachable -- and many users think so. That's because removing the cable with your hands seems impossible, but luckily the cable can be detached from the monitor. , Apple has a special tool for extracting information from its new StudioDispl
How to solve the problem that the Springboot2 session timeout setting is invalid
May 22, 2023 pm 01:49 PM
Problem: Today, we encountered a setting timeout problem in our project, and changes to SpringBoot2’s application.properties never took effect. Solution: The server.* properties are used to control the embedded container used by SpringBoot. SpringBoot will create an instance of the servlet container using one of the ServletWebServerFactory instances. These classes use server.* properties to configure the controlled servlet container (tomcat, jetty, etc.). When the application is deployed as a war file to a Tomcat instance, the server.* properties do not apply. They do not apply,
