PHP swoole (1.安装与demo)

1.简介:

• swoole是php的一类扩展;
• swoole用以处理异步及多线程业务场景;
• swoole支持TCP、UDP、UnixSocket 3种协议，支持IPv4和IPv6，支持SSL/TLS单向双向证书的隧道加密;
• 官网:
• 中文:
• API文档:
• github:

2.安装(ver Linux):

• 需要支持:
  Version-1: PHP 5.3.10 or later
  Version-2: PHP 5.5.0 or later
  Linux, OS X and basic Windows support
  GCC 4.4 or later

• 安装方式1:使用pecl安装

pecl install swoole

• 安装方式2:源码安装

sudo apt-get install php5-dev
git clone 
cd swoole-src
phpize
./configure
make && make install

• 更改PHP配置,引用swoole.so扩展:

sudo vi /etc/php/cli/php.ini

extension=swoole.so

• 重启php及nginx service;
• 查看PHP是否引用扩展:

php -m
或
php -r "echo(phpinfo());"

3.示例:

• Server:

// create a server instance
$serv = new swoole_server("127.0.0.1", 9501);

// attach handler for connect event, once client connected to server the registered handler will be executed
$serv->on('connect', function ($serv, $fd){
    echo "Client:Connect.\n";
});

// attach handler for receive event, every piece of data received by server, the registered handler will be
// executed. And all custom protocol implementation should be located there.
$serv->on('receive', function ($serv, $fd, $from_id, $data) {
    $serv->send($fd, $data);
});

$serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";
});

// start our server, listen on port and be ready to accept connections
$serv->start();

• Client:

$client = new swoole_client(SWOOLE_SOCK_TCP);
if (!$client->connect('127.0.0.1', 9501, 0.5))
{
    die("connect failed.");
}

if (!$client->send("hello world"))
{
    die("send failed.");
}

$data = $client->recv();
if (!$data)
{
    die("recv failed.");
}

$client->close();

• 关闭进程(shell)

#! /bin/bash
ps -eaf |grep "server.php" | grep -v "grep"| awk '{print $2}'|xargs kill -9

• 正确输出:

php swoole_server.php 
Client: Connect.
Client: Close.

Server: hello world
