PHP-FPM Performance Optimization: Measures to Improve Website Security and Stability
With the rapid development of the Internet, website performance optimization has become more and more important. . In PHP development, PHP-FPM (FastCGI Process Manager) is a common PHP solution used to improve performance and website stability. However, it is not enough to simply install and configure PHP-FPM. Some measures need to be taken to further optimize performance and improve the security and stability of the website. This article will introduce some specific code examples to help you better implement PHP-FPM performance optimization.
- Configuring the PHP-FPM process pool
First, we need to configure the PHP-FPM process pool reasonably. By adjusting parameters such as the number of processes and the maximum number of requests, PHP-FPM can better meet the needs of the website. The following is an example PHP-FPM process pool configuration:
[www] user = www-data group = www-data listen = /var/run/php/php7.4-fpm.sock listen.owner = www-data listen.group = www-data pm = dynamic pm.max_children = 20 pm.start_servers = 5 pm.min_spare_servers = 2 pm.max_spare_servers = 8 pm.process_idle_timeout = 10s pm.max_requests = 500
In this example, we use the dynamic process management mode (pm = dynamic) and set the maximum number of child processes to 20 (pm.max_children) , the initial number of child processes is 5 (pm.start_servers), the minimum number of idle child processes is 2 (pm.min_spare_servers), the maximum number of idle child processes is 8 (pm.max_spare_servers), and the idle process timeout is 10 seconds (pm.process_idle_timeout ), the maximum number of requests is 500 (pm.max_requests).
According to the actual website load, these parameters can be adjusted as needed. By properly configuring the PHP-FPM process pool, performance and resource consumption can be better balanced.
- Using OPcache
OPcache is a built-in extension of PHP that is used to cache and improve the execution performance of PHP scripts. Enabling OPcache can greatly reduce the compilation time of PHP scripts and reduce the load on the server. The following is an example OPcache configuration:
[opcache] zend_extension=opcache.so opcache.enable=1 opcache.enable_cli=1 opcache.memory_consumption=128 opcache.interned_strings_buffer=8 opcache.max_accelerated_files=4000 opcache.validate_timestamps=0 opcache.revalidate_freq=60
In this example, we enabled OPcache (opcache.enable=1), set the memory consumption to 128MB (opcache.memory_consumption), and the interned string buffer is 8MB (opcache.interned_strings_buffer), the maximum number of cached files is 4000 (opcache.max_accelerated_files), the timestamp verification of the script is canceled (opcache.validate_timestamps=0), and the revalidation frequency is set to 60 seconds (opcache.revalidate_freq) .
By using OPcache, the execution performance of PHP scripts can be greatly improved and the load on the server can be reduced.
- Turn on PHP security settings
In order to improve the security of the website, we also need to turn on some PHP security settings. The following are some common examples of PHP security settings:
display_errors = Off allow_url_fopen = Off expose_php = Off open_basedir = /var/www/html:/tmp disable_functions = exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source
In this example, we turn off error display (display_errors = Off), disable remote file operations (allow_url_fopen = Off), and hide PHP version information (expose_php = Off), set directory-based access restrictions for PHP (open_basedir = /var/www/html:/tmp), and disable some dangerous PHP functions (disable_functions).
By turning on these security settings, you can effectively reduce the risk of website attacks and improve website security.
Summary:
By properly configuring the PHP-FPM process pool, using OPcache, and turning on PHP security settings, you can further optimize the performance of PHP-FPM and improve the security and stability of the website. The above are just some simple examples, and the specific configuration needs to be adjusted according to the actual situation. Through continuous optimization and improvement, we can make PHP-FPM perform better and provide users with a better website experience.

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.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
