请Nginx服务器专家帮忙解答下:生产环境下,考虑效率和安全,如何配置nginx.conf ?
例如:
<code> server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m; </code>
<code> fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; </code>
这些设置的作用是什么呢?

这些设置的作用是什么呢?
fastcgi_connect_timeout 设置连接后端服务的超时时间,注意时连接超时。
fastcgi_send_timeout 定义发送数据到后端服务的超时时间。
fastcgi_read_timeout 定义应用程序FastCGI的响应时间,如果这个时间段内Nginx没有收到响应,返回504。
fastcgi_buffer_size 设置缓冲区大小,默认一个缓冲区大小。
fastcgi_buffers 设置缓冲区的数量和大小。
fastcgi_busy_buffers_size 设忙时置缓冲区大小,一般是fastcgi_buffer_size的2倍。
fastcgi_temp_file_write_size 提供使用磁盘上的临时文件时,设置写缓冲区的大小。
以上设置默认即可。

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
