php强大的时间转换函数strtotime,php函数strtotime
使用strtotime可以将各种格式的时间字符串转换为时间戳
转换常规时间格式
echo date('Y-m-d H:i:s', strtotime('2016-01-30 18:00')).PHP_EOL; echo date('Y-m-d H:i:s', strtotime('20160130180001')).PHP_EOL;
转换自然时间描述
//昨天 echo date('Y-m-d H:i:s', strtotime('yesterday')).PHP_EOL; //上周 echo date('Y-m-d H:i:s', strtotime('last week')).PHP_EOL; //本周开始时间 echo date('Y-m-d H:i:s', strtotime('this week midnight')).PHP_EOL; //本月开始时间 echo date('Y-m-d H:i:s', strtotime('first day of this month midnight')).PHP_EOL; //计算相对时间 echo date('Y-m-d H:i:s', strtotime('+1 month')).PHP_EOL;

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
