了解 HTML、CSS、JavaScript 和 PHP： 非技术指南
Chan网络开发的世界听起来可能令人生畏，但了解其基础语言–HTML、CSS、JavaScript 和 PHP–可以简化任何人的工作。这些语言在创建网站和应用程序的过程中发挥着不同的作用。以下是详细介绍：
Table of Contents
超文本标记语言（HTML）
它是什么：HTML 是任何网页的支柱。可将其视为提供在线内容结构的蓝图。
功能： 它定义了网页的布局和元素，如标题、段落、图像和链接。
使用示例： 当你看到一个网站的标题或可点击链接时，这就是 HTML 在起作用。
类比： 如果网站是一座房子，HTML 就是砖块和墙壁。
CSS （层叠样式表）
它是什么：CSS 是网站的设计艺术家。它通过为 HTML 结构设计样式，使网页看起来更具视觉吸引力。
功能： 它管理颜色、字体、布局和响应性（网页如何适应不同设备）。
使用示例： 当你欣赏一个网站的时尚色彩或现代设计时，这就是 CSS 的幕后功劳。
类比： 如果 HTML 是房子，那么 CSS 就是油漆、窗帘和装饰。
JavaScript
它是什么：JavaScript 为网页增添了互动性，使网页充满活力，引人入胜。
功能： 它允许使用弹出窗口、动画图形和交互式表单等功能。JavaScript 可直接在浏览器中运行，React 或 Vue.js 等框架可增强其功能。
使用示例： 当你将鼠标悬停在一个按钮上，它就会改变颜色，或者填写表格时，你就会看到实时建议，这就是 JavaScript 的作用。
类比： 如果 HTML 是房子，CSS 是装饰，那么 JavaScript 就是电，它能让电灯和小工具等东西工作。
PHP（超文本预处理程序）
它是什么：PHP 是一种服务器端脚本语言，用于处理网站后台。
功能： 它管理数据库、用户登录和动态内容生成。WordPress 等平台在很大程度上依赖于 PHP。
使用示例： 当您登录网站或提交表单时，PHP 会在幕后处理您的数据。
类比： PHP 就像房子里的管道，管理着隐藏空间里发生的事情，使一切运行顺畅。
HTML、CSS、JavaScript 和 PHP 的区别
总结： 编程语言为何重要
每个网站都将这些语言结合在一起，以创建无缝的用户体验。无论是设计博客样式、添加动态菜单，还是处理安全交易，这些语言都是现代网络开发的拼图。
通过学习 HTML、CSS、JavaScript 和 PHP 的基础知识，你将对网络的复杂性有更深刻的认识，甚至可能激发你建立自己网站的灵感！

What Determines IPv4 Pricing in Today’s Market?
Scarcity, shifting demand, and leasing platforms such as i.lease are reshaping how IPv4 addresses are valued and traded globally. IPv4 pricing is driven primarily by scarcity, block size, and fluctuating demand across regions and industries. Leasing models, including platforms like i.lease, are stabilising costs amid volatile purchase markets.
