Article Introduction：It is not difficult to learn PHP from scratch. The key is to clarify the direction and follow the steps. First of all, it is necessary to clarify that PHP is mainly used for dynamic web development, which is especially suitable for interaction with databases, such as implementing user registration, login and other functions. The first step is to build an environment. It is recommended to use XAMPP or phpStudy to quickly run PHP files, and to improve efficiency with editors such as VSCode. When learning grammar, you should focus on mastering the basic structure, including conditional judgment, loops, function definitions and array operations, and you don’t have to memorize everything by rote. Finally, you need to practice through small projects, such as leaving a message book or logging into the system, contact form submission, database connection, and data addition, deletion, modification and inspection, and gradually improve your practical capabilities.

Article Introduction：Adding comments to HTML can improve code readability and teamwork efficiency. Because HTML is a structured markup language and lacks obvious logical processes, it is difficult to understand the role of blocks when the page is complex. At this time, the comments can be used as "navigation" to answer questions such as module purpose, dynamic content source, form behavior, etc. Effective comments should be clear and concise, and use syntax. Common methods include explaining the purpose of the module (such as), marking precautions or to-do items (such as), marking code segment boundaries, and avoiding redundant explanations. Scenes suitable for annotation include page structure partitions, complex nesting areas, elements that require special processing and template reference locations. The unified annotation style is better when collaborating with teams, such as whether to use abbreviations, alignment, specific keywords, etc., which will help maintain and understand for a long time.
