本文实例讲述了php自动更新版权信息显示的方法。分享给大家供大家参考。具体分析如下:
我们一般会在页面下方输出版权信息,包含年份信息,每年都要修改,这段简单的代码帮你解决这个问题,自动更新年份
function autoUpdatingCopyright($startYear){ // given start year (e.g. 2004) $startYear = intval($startYear); // current year (e.g. 2007) $year = intval(date('Y')); // is the current year greater than the // given start year? if ($year > $startYear) return $startYear .'-'. $year; else return $startYear; } //用法: print '© ' . autoUpdatingCopyright(2001) . ' bitsCN.com'; /* Output: (c) 2001-2012 bitsCN.com */
希望本文所述对大家的php程序设计有所帮助。

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.
