需求:用户在后台添加文章时可以选择发布的方式:立即发布,指定时间发布。
分析:
1、数据库表设计:
ctime[int 11] 发布时间
status[tiny int 2] 发布状态,0-禁用 1-正常在用、显示 2-计划发布
2、php方法:
用户使用立即发布,则存储时status=1,前台显示只要查到status=1的就可以直接显示了
用户选择定时发布,则储存时status=2,此时前台是不显示的
写另外一个task.php文件,去表中查status=2的记录,判断ctime和当前时间,当ctime大于当前时间时,就将记录的status设置为1
3、在linux服务器上新建一个定时任务
这个定时任务每隔一段时间就去执行task.php。
假设我们每分钟去执行下文件,使用crontab来设定一个每分钟执行的任务,关于crontab使用方法,自行百度“linux crontab”
编辑系统的定时任务:
crontab -e<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"> </span>
*/1 * * * * curl http://www.test.com/task.php
使用crontab -l 可以查看任务列表
注意:!!!!!!!!!!!!!!!!!!
如果连接中带有参数,如:http://www.baidu.com/index.php?m=test&=test
请转义为:http://www.baidu.com/index.php?m=test\&=test
对!一定要加上反斜杠

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
