How to use PHP-FPM optimization to improve the performance of CodeIgniter applications
Introduction:
When developing Web applications, performance is a very important consideration. Under the CodeIgniter framework, application performance can be significantly improved through reasonable configuration and optimization. This article will introduce how to use PHP-FPM to optimize the performance of CodeIgniter applications and provide specific code examples.
1. Introduction to PHP-FPM
PHP-FPM (FastCGI Process Manager) is a tool for managing PHP processes and can improve the performance of PHP applications. It manages PHP processes independently and provides functions such as process pool and process management.
2. Combination of PHP-FPM and CodeIgniter
- Installing PHP-FPM
First, make sure that PHP and PHP-FPM have been installed on the server. After the installation is complete, make some configuration adjustments. - Configuring PHP-FPM
Open the PHP-FPM configuration file php-fpm.conf and adjust it according to the actual situation of the server. The following are some commonly used configuration items:
pm = dynamic pm.max_children = 10 pm.start_servers = 5 pm.min_spare_servers = 3 pm.max_spare_servers = 8 pm.max_requests = 1000
Parameter explanation:
- pm: process management mode, dynamic means dynamic mode.
- pm.max_children: The maximum number of processes in the process pool.
- pm.start_servers: Number of processes at startup.
- pm.min_spare_servers: Minimum number of idle processes.
- pm.max_spare_servers: Maximum number of idle processes.
- pm.max_requests: The number of requests processed by a process. It will be restarted after reaching this value.
- Configure CodeIgniter
Open CodeIgniter’s configuration file config.php and make the following configuration:
$config['index_page'] = ''; $config['uri_protocol'] = 'REQUEST_URI';
Set index_page to empty to remove the URL index.php; Set uri_protocol to REQUEST_URI to let CodeIgniter use a more efficient URI processing method.
- Code Example
The following is a sample code that demonstrates how to use the features of PHP-FPM in CodeIgniter.
<?php class Welcome extends CI_Controller { public function index() { $this->load->view('welcome_message'); } public function process_request() { $data = $this->input->post('data'); $result = $this->heavy_processing($data); echo $result; } private function heavy_processing($data) { // 一些耗时的处理逻辑 return $result; } }
In the above example, by putting the time-consuming processing logic into the independent function heavy_processing, we can use the process pool mechanism of PHP-FPM to process multiple requests concurrently, improving the application's processing capability and response. speed.
Conclusion:
Through reasonable configuration and optimization, combining PHP-FPM with CodeIgniter can greatly improve the performance of the application. By adjusting the configuration parameters of PHP-FPM and rationally utilizing the process pool mechanism, more efficient request processing and concurrent processing capabilities can be achieved.
Summary:
When developing web applications, optimizing performance is an important consideration. By combining PHP-FPM and CodeIgniter, we can effectively improve the performance of the application. By properly configuring PHP-FPM and taking advantage of its process management and concurrent processing features, the application's responsiveness and processing speed can be significantly improved.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

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),
