How to make the page static in php
页面静态化的好处
根据不同情况,有些需要生成静态页,有些实现伪静态即可,根据实际需求进行抉择。而静态化的好处,总结下来有以下几点:
● 提高访问速度
● 减少服务器压力
● 有利于SEO
● 提升网站稳定性
PHP生成静态页
PHP生成静态页有多种方法,此次使用的是ob系列函数,函数内容可查看官方手册。
<?php $website = $_GET['website']; ob_start();// 打开输出缓存 $content = file_get_contents('http://www.'.$website.'.com'); echo $content;// 输出内容,此部分的内容为静态页的内容 file_put_contents('./'.$website.'.html', ob_get_contents()); ob_end_clean();// 关闭 echo $content;
Rewrite重写规则
在.htaccess中实现Rewrite重写规则,至于使用.htaccess是否影响效率不在讨论范围之内。
RewriteEngine on # 如果有符合条件的静态页,返回静态页 RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f # 路由重写 RewriteRule ^(\w+).html$ /index.php?website=$1
测试
此时访问域名www.youWebsite.com/baidu.html,由于没有静态页,相当于请求到www.youWebsite.com/index.php?website=baidu。通过PHP的处理,已经生成baidu.html文件。
再次访问www.youWebsite.com/baidu.html,这时由于存在baidu.html文件,直接返回静态页,而不再请求PHP。
有几点注意事项:
● 检查apache是否开启Rewrite
● Linux下文件权限

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5.

Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
