PHP componentized programming skills

However, its UI is not convenient, not only PHP, but any webProgramming LanguageThere are similar issues in UI design. The host language and HTML are mixed in a file, and a large number of repeated htmlCode, Without any technical content, but it is very time-consuming and labor-intensive. So I want to summarize and summarize the UI of the PHP project I have previously done, and encapsulate it into small components (just like those in Delphi ), the interface is presented in a unified style. You can write multiple CSS files for this component in the future to provide the "skin-changing" function.

All components are inherited fromAbatractcomponentAnd implementTostring ()AndRender ()Method.AbatractcomponentThere are three main child classes, one of which is the container class.ContinerIs derived fromPanel,PoppanelAndGrouppanelClass. The second is the control class.ControlIs the parent class of all visual control classes, suchButton,LinkbuttonClass. The third is the list class.ListTo implement the UI with list and name-value pairs.

Some codes of abstractcomponent:
