How to switch php running mode from fpm-fcgi to cli
When using a php crawler, you must use the cli environment
I checked the current php version information as follows:
I print PHP_SAPI
show fpm-fcgi
How to become cli
The server environment is linux+nginx
Supplement: Can I understand that cli must be in command line mode?
Just tested PHP_SAPI
in the command line and output cli
Question: Can http simulation call be implemented to implement cli

CLI = command-line interface = command line interface
You can use popen or proc_open in php-fpm to asynchronously call php-cli to execute a php script, such as:
<code>例子1(popen): <?php function foo() { echo date('Y-m-d H:i:s')."\n"; echo shell_exec('php -r \'sleep(1); echo date("Y-m-d H:i:s")." by shell_exec:blocking\n";\''); //阻塞 $pipe1 = popen('php -r \'sleep(2); echo date("Y-m-d H:i:s")." by popen1:non-blocking\n";\'', 'r'); //非阻塞(管道) $pipe2 = popen('php -r \'sleep(1); echo date("Y-m-d H:i:s")." by popen2:non-blocking\n";\'', 'r'); //非阻塞(管道) echo date('Y-m-d H:i:s')."\n"; register_shutdown_function(function() use ($pipe1, $pipe2) { //事件驱动(脚本结束事件),异步回调 echo stream_get_contents($pipe1); //输出子进程返回的数据 echo stream_get_contents($pipe2); //输出子进程返回的数据 pclose($pipe1); pclose($pipe2); }); } foo(); //输出 2016-09-11 20:25:30 2016-09-11 20:25:31 by shell_exec:blocking 2016-09-11 20:25:31 2016-09-11 20:25:33 by popen1:non-blocking 2016-09-11 20:25:32 by popen2:non-blocking 例子2(proc_open): PHP用proc_open新建子进程使用管道通信非阻塞执行PHP脚本. 脚本结束时register_shutdown_function回调函数访问管道获取子进程输出的数据. <?php function foo() { $proc = proc_open( //task.php 内容为 $arr = unserialize(stream_get_contents(STDIN)); $arr['time'] = date('Y-m-d H:i:s', $arr['time']); echo serialize($arr); '/png/php/5.4.45/bin/php /home/eechen/task.php', array( 0 => array('pipe','r'), //stdin (用fwrite写入数据给管道) 1 => array('pipe','w'), //stdout(用stream_get_contents获取管道输出) 2 => array('pipe','w'), //stderr(用stream_get_contents获取管道输出) //2 => array('file','/tmp/err.txt','a') //stderr(写入到文件) ), $pipes, //管道(stdin/stdout/stderr) '/tmp', //当前PHP进程的工作目录 array('foo' => 'bar') //php.ini 配置 variables_order = "EGPCS" 其中E表示$_ENV,否则$_ENV输出为空 ); //var_dump($pipes); //resource of type (stream) if(is_resource($proc)) { //stdin $stdin = serialize(array('time' => time())); fwrite($pipes[0], $stdin); //把参数传给脚本task.php fclose($pipes[0]); //fclose关闭管道后proc_close才能退出子进程,否则会发生死锁 register_shutdown_function(function() use($pipes, $proc) { //事件驱动(脚本结束事件),异步回调 //stdout $stdout = stream_get_contents($pipes[1]); fclose($pipes[1]); //stderr $stderr = stream_get_contents($pipes[2]); fclose($pipes[2]); //exit code (返回进程的终止状态码,如果发生错则返回-1) $status = proc_close($proc); $data = array( 'stdout' => $stdout, 'stderr' => $stderr, 'status' => $status, ); var_export($data); //echo json_encode($data); }); } } foo(); //输出: array ( 'stdout' => 'a:1:{s:4:"time";s:19:"2016-09-11 21:26:29";}', 'stderr' => '', 'status' => 0, )</code>
cli is the command line, and under Linux it is the php
command. There are many ways to execute the command line in php. You can use functions such as exec
to execute it synchronously. There are also methods to execute it asynchronously. Please read the documentation in detail
Just run the script directly using the terminal

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

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 and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

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 is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
