You can use non-blocking sockets and one of pecl extensions for PHP:

• http://php.net/event
• http://php.net/libevent
• http://php.net/ev
• https://github.com/m4rw3r/php-libev

You can use library which gives you an abstraction layer between your code and a pecl extension: https://github.com/reactphp/event-loop

You can also use async http-client, based on the previous library: https://github.com/reactphp/http-client

See others libraries of ReactPHP: http://reactphp.org

Be careful with an asynchronous model. I recommend to see this video on youtube: http://www.youtube.com/watch?v=MWNcItWuKpI
