Example of php asynchronous processing task function based on swoole

This paper describes the asynchronous processing task function of php based on swoole. Share it for your reference, as follows:

Install swoole:

Download the official swoole compressed package and unzip it into the directory

$ cd swoole             #  Enter  swoole  Directory 
$ phpize
$ ./configure --with-php-config=/usr/local/php/bin/php-config  # Pay attention to see if this path exists on the server 
$ make && make install

Modify the php. in file

vi /usr/local/php/lib/php.ini

Add the following

extension = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/swoole.so" // Different versions may have different paths 

Restart php-fpm after saving

$ /etc/init.d/php-fpm restart

The php-m command will see if the addition is successful and you will see an swoole module

$ php -m

As a daemon monitoring task, the server creates a new server. php:

<?php
$serv = new Swoole\Server("127.0.0.1", 9502);
$serv->set(array('task_worker_num' => 4));
$serv->on('Receive', function($serv, $fd, $from_id, $data) {
  $task_id = $serv->task("Async");
  echo "Dispath AsyncTask: id=$task_id\n";
});
$serv->on('Task', function ($serv, $task_id, $from_id, $data) {
  echo "New AsyncTask[id=$task_id]".PHP_EOL;
  $serv->finish("$data -> OK");
});
$serv->on('Finish', function ($serv, $task_id, $data) {
  echo "AsyncTask[$task_id] Finish: $data".PHP_EOL;
}); 
$serv->start();

Open in command-line mode

php server.php

Create a new client. php

<?php
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);
$client->on("connect", function(swoole_client $cli) {
  $cli->send("GET / HTTP/1.1\r\n\r\n");
});
$client->on("receive", function(swoole_client $cli, $data){
  echo "Receive: $data";
  $cli->send(str_repeat('A', 100)."\n");
  sleep(1);
});
$client->on("error", function(swoole_client $cli){
  echo "error\n";
});
$client->on("close", function(swoole_client $cli){
  echo "Connection close\n";
});
$client->connect('127.0.0.1', 9502);

Open a new window for command line execution

php client.php

After execution, you will find that information will be output in the window of server. php
