Course Introduction:Annotation-based route parsing and dynamic controller loading implementation in PHP As the complexity of web applications continues to increase, route management and controller loading have become an important part of the development process. The traditional route resolution and controller loading methods require manual configuration of routing rules and controller classes, and require frequent updates and maintenance, which can become very cumbersome and inefficient in large applications. To solve this problem, annotations can be used to simplify route parsing and dynamic controller loading. Annotations are a way to add relevant metadata to your code

Course Introduction:Whether CSS loading blocks page rendering is a common question. This article will explore in detail the impact of CSS loading on page rendering and provide specific code examples for demonstration. First, we need to know how CSS loading affects page rendering. When the browser parses HTML, if it encounters an external CSS file, the browser will pause the parsing of the HTML and then start downloading the CSS file. Only after the CSS file is downloaded and parsed by the browser will the browser continue parsing the HTML. This means that CSS loads
