PHP解释器模式的一个简单示例分享
简介:PHP解释器模式的一个简单示例分享
简介:css中position是一个非常的重要的属性,它有absolute(绝对定位)、relative(相对定位)、static(静态定位,默认值)、fixed(固定定位)四种。通过position属性,我们可以让元素相对于其正常位置,父元素或者浏览器窗口进行偏移。
简介:定位,指确定方位;确定或指出的地方;确定场所或界限(如通过勘察)给这个地产的界限定位。 在CSS中关于定位的内容是:position:relative | absolute | static | fixed。static 没有特别的设定,遵循基本的定位规定,不能通过z-index进行层次分级。在本文流中,任何一个元素都被文本流所限制了自身的位置,但是通过CSS我们依然使得这些元素可以改变自己的位置,我们可以通过float来让元素浮动,我们也可以通过margin来让元素产生位置移动。

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.
