Swoole WebSocket聊天室

安装Swoole

过程中使用pecl install swoole进行安装swoole,所以要求php版本大于7.0.0
如果已经安装了5.4或者其他版本可以进行卸载低版本

rpm -qa |grep php|xargs rpm -e

更新yum源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

查看php7.x可用版本

yum serach php7

安装

yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml

查看7.x版本是否已安装

php -v

安装pecl

yum install php72w-pear

用pecl安装swoole

pecl install swoole

在php.ini添加extension=swoole.so
执行

php -m

如果有swoole就成功了

官网demo socket.php

on('open', function (swoole_websocket_server $server, $request) {
    file_put_contents( __DIR__ .'/log.txt' , $request->fd);
});

$server->on('message', function (swoole_websocket_server $server, $frame) {
    global $client;
    $data = $frame->data;
    $m = file_get_contents( __DIR__ .'/log.txt');
    for ($i=1 ; $i<= $m ; $i++) {
        echo PHP_EOL . '  i is  ' . $i .  '  data  is '.$data  . '  m = ' . $m;
        $server->push($i, $data );
    }

});

$server->on('close', function ($ser, $fd) {
    echo "client {$fd} closed\n";
});

$server->start();
