致命错误:调用未定义函数socket_create() [英] Fatal error: Call to undefined function socket_create()

问题描述

我的代码是这样的:

if( ($this->master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0 )

    {
    die("socket_create() failed, reason: ".socket_strerror($this->master));
    }

当我运行与网络套接字建立连接的php文件时，出现错误 致命错误:调用该行中未定义的函数socket_create() if(($ this-> master = socket_create(AF_INET，SOCK_STREAM，SOL_TCP))< 0)

when I run my php file which create connection with web socket, I got error Fatal error: Call to undefined function socket_create() in the line if( ($this->master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0 )

因此，我无法连接Web套接字，也无法从套接字获取响应消息，因为运行客户端页面时浏览器中显示的是套接字状态:3(关闭).

Therefore i am not able to connect web socket and also not able to get response message from socket because Socket Status: 3 (Closed) is displaying in my browser when run client page .

您知道缺少什么吗? 预先谢谢你.

Have you got an idea what is missing? Thank you in advance.
