Apache下禁止php文件被直接访问的方法
一开始,我想在重写规则里直接禁止php后缀的URL被访问。但后来发现重写规则是递归调用的,如果在重写规则里直接禁止php,那么重写到php文件的规则也会失效。RewriteEngineOn
RewriteRule^test$/test.php[L]
RewriteRule^test.php$$0[F,L]
递归调用这真可怕,一开始访问/test的时候URL重写检查一次,然后匹配到^test$就内部重定向到/test.php,然而内部重定向也会触发URL重写,因此再次检查,匹配到^test.php$,被强制直接[F](Forbidden)操作,所以就变成了403错误。既然这样,就必须判是否已经经过服务器重定向。这时候服务器变量里有个REDIRECT_URL可以使用,因此我试着用这个做判断。
RewriteEngineOn
RewriteRule^test$/test.php[L]
RewriteCond%{REDIRECT_URL}^$
RewriteRule.*$0[F,L]这样写访问/test依旧被403,稍微检查下,发现RewriteCond中%{REDIRECT_URL}永远为空,这就蛋疼了,这样的话在重写规则中没办法直接禁止php了。但是可以用不怎么华丽的方法实现。就是在php文件中去判断REDIRECT_URL,虽然这个方法可以实现,但是感觉很逊,只是目前为止也没找到什么更好的办法了。
$_SERVER['REDIRECT_URL']ordie('Forbidden');
//这里只是显示文字而已,实际使用的时候还需输出的HTTP错误代码。
echo$_SERVER['REDIRECT_URL'];//成功访问显示信息
?>
把这段PHP代码修改下丢进全局引用里就基本上没啥问题了,虽然不是完美解决,但是至少还是解决了,以后也许会发现更好的方法。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

NGINX and Apache each have their own advantages and disadvantages, and the choice should be based on specific needs. 1.NGINX is suitable for high concurrency scenarios because of its asynchronous non-blocking architecture. 2. Apache is suitable for low-concurrency scenarios that require complex configurations, because of its modular design.

Laravel optimizes the web development process including: 1. Use the routing system to manage the URL structure; 2. Use the Blade template engine to simplify view development; 3. Handle time-consuming tasks through queues; 4. Use EloquentORM to simplify database operations; 5. Follow best practices to improve code quality and maintainability.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.
