php regulators include Opcode cache, database connection pool, asynchronous programming, caching system, concurrent processing, security protection, performance analysis tools, coding standards and optimization, etc. Detailed introduction: 1. Opcode cache, a tool that compiles PHP code into machine code and caches it; 2. Database connection pool, the application obtains a database connection from the connection pool when needed, instead of re-establishing the connection every time; 3. Asynchronous programming can convert some time-consuming operations into non-blocking methods, thereby improving the concurrent performance of the program; 4. Cache system, etc.
The operating environment of this article: Windows 10 system, PHP8.1.3 version, Dell G3 computer.
PHP regulator refers to a tool, library or technology that can optimize, enhance or improve the performance of PHP programs. The following are some common PHP tuners:
Opcode cache: Opcode cache is a tool that compiles PHP code into machine code and caches it. It can reduce the parsing and compilation time of PHP code and improve the execution speed of the program. Common Opcode caches include APC, Zend OPcache and XCache.
Database connection pool: Database connections are one of the common bottlenecks in web applications. Database connection pooling allows an application to obtain a database connection from the connection pool when needed instead of re-establishing the connection each time. This can reduce the overhead of connection establishment and disconnection and improve the performance of database access. Common database connection pools include MySQL Proxy, ProxySQL, and pgBouncer.
Asynchronous programming: PHP is natively a synchronous language, that is, each request blocks and waits for the result to be returned. Asynchronous programming can convert some time-consuming operations into non-blocking methods, thereby improving the concurrency performance of the program. Common asynchronous programming frameworks include Swoole and ReactPHP.
Caching system: Caching temporarily stores calculation results so that subsequent requests can quickly obtain them. Commonly used caching systems in PHP include Memcached and Redis. By using these caching systems, time-consuming operations such as database queries can be reduced and the response speed of the program can be improved.
Concurrency processing: PHP native performance is low when processing concurrent requests. A common solution is to use multiple processes or threads to handle concurrent requests. Common multi-process and multi-thread frameworks include Swoole and Workerman.
Security protection: PHP programs often face various security threats, such as SQL injection, cross-site scripting attacks, etc. In order to improve the security of the program, you can use some security protection tools and technologies, such as filtering user input, using precompiled statements, using security frameworks, etc.
Performance analysis tools: Performance analysis tools can help developers find performance bottlenecks and optimization points in PHP programs. Common performance analysis tools include Xdebug, Blackfire, and New Relic.
Coding specifications and optimization: Good coding specifications and optimization skills can improve the performance of PHP programs. For example, avoid using global variables, reduce the number of database queries, use appropriate data structures, etc.
Summary
PHP adjusters include Opcode cache, database connection pool, asynchronous programming, caching system, concurrent processing, security protection, performance analysis tools, and coding standards and Optimization etc. By using these regulators, the performance and security of PHP programs can be improved.
