php socket编程通信

Jun 23, 2016 pm 01:28 PM

今天终于测试成功了php中的socket通信,先看原理图


这里可以清晰的看到socket到底是在网络模型中的哪个位置,还有与端口的形象表示

我们编程就是按这个顺序的,请看下面的图

这下我们好写程序了,先看Server端   保存为serverSocket.php

[php] view plain copy print ?

  
再来看Client客户端的代码  保存为client.php

[php] view plain copy print ?

  
注意事项:  1  测试socket的时候必须要确定你是否开启socket扩展库,如果没有请到php.ini中找到extension_dir=php_sockets.dll,把                            前面的分号去掉

                      2  测试时,在浏览器中输入http://localhost/serverSocket.php  和http://localhost/client.php  ,现在问题就来了,到底先运                             行哪个呢,因为 客户端要回应,所以我们先运行server再运行client  ,这样你就能看到结果了。
