PHP实现Websocket异步客户端 (workerman方式)
1. 通过composer load workman
composer安装
php -r "readfile('https://getcomposer.org/installer');" | php
mv composer.phar /usr/local/bin/composer
mkdir /home/wsclient
cd /home/wsclient
composer require workerman/workerman
若出错,一般是 Composer 未配置正确的源,可以尝试切换Composer到官方源
composer config --global --unset repos.packagist
composer install
2. 创建workerman执行文件 /home/wsclient/wsclient.php
本例使用NowAPI提供的消息推送服务 Websocket消息推送服务

3. 运行
本例需要php_openssl支持,注意在php.ini中添加php_openssl ext
/usr/bin/php /home/wsclient/wsclient.php start
如果不想配置PHP运行环境,也可以直接用swoole编译好的二进制版
/usr/bin/swoole-cli /home/wsclient/wsclient.php start
