The main content of this article is to use PHP to implement asynchronous requests and ignore return values. It has certain reference value. Friends in need can take a look. I hope it will be helpful to you.
Project needs, the scenario is as follows:
Under certain conditions, the interface needs to be called to send multiple requests to execute the script, but since the script execution time under each request is about half an hour, so Give up and return the execution result. It only requires that it can be sent within seconds.
The code is as follows:
/** * 发起异步请求,忽略返回值 * @param $url 请求url * @return bool */ function asyncPost($url) { $args = parse_url($url); //对url做下简单处理 $host = $args['host']; //获取上报域名 $path = $args['path'] . '?' . $args['query'];//获取上报地址 $fp = fsockopen($host, 80, $error_code, $error_msg, 1); if (!$fp) { Log::record('获取错误信息:'.$error_code . ' _ ' . $error_msg, Log::INFO, true); Log::save('',LOG_PATH . '_' . date('y_m_d') . '.txt'); return false;// } else { stream_set_blocking($fp, true);//开启了手册上说的非阻塞模式 stream_set_timeout($fp, 1);//设置超时 $header = "GET $path HTTP/1.1\r\n"; //注意 GET/POST请求都行 我们需要自己按照要求拼装Header http协议遵循1.1 $header .= "Host: $host\r\n"; $header .= "Connection: close\r\n\r\n";//长连接关闭 fputs($fp, $header); fclose($fp); } }
The example is as follows:
$url[0] = "http://XXXX/demo.php?a=1&b=2&c=3&d=4&e=5"; $url[1] = "http://XXXX/demo.php?a=1&b=2&c=3&d=4&e=5"; $url[2] = "http://XXXX/demo.php?a=1&b=2&c=3&d=4&e=5"; $url[3] = "http://XXXX/demo.php?a=1&b=2&c=3&d=4&e=5"; $url[4] = "http://XXXX/demo.php?a=1&b=2&c=3&d=4&e=5"; $url[5] = "http://XXXX/demo.php?a=1&b=2&c=3&d=4&e=5"; foreach($url as $k=>$val){ asyncPost($val); }
The result is as follows:
The above is me The results of multiple tests, the time range is as above.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
