Fatal error: Call to undefined function socket_create()
提问by Sanjeev Kumar Jha
My code is like this:
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));
}
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( ($this->master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0 )
当我运行创建与 Web 套接字连接的 php 文件时，出现错误 Fatal error: Call to undefined function socket_create() in the line if( ($this->master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0 )
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 .
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，我的浏览器中显示 Socket Status: 3 (Closed)。
Have you got an idea what is missing? Thank you in advance.
你知道缺少什么吗？先感谢您。

For a typical XAMPP install on windows you probably have the php_sockets.dll in your C:\xampp\php\ext directory. All you got to do is go to php.ini in the C:\xampp\php directory and change the ;extension=php_sockets.dllto extension=php_sockets.dll.
对于 Windows 上的典型 XAMPP 安装，您的 C:\xampp\php\ext 目录中可能有 php_sockets.dll。所有你要做的就是去为php.ini在C：\ XAMPP \ php目录，并更改;extension=php_sockets.dll到extension=php_sockets.dll。

If you are using xampp 7.3.9. socket already installed. You can check xampp\php\ext and you will get the php_socket.dll. if you get it go to your xampp control panel open php.ini file and remove (;) from extension=sockets.
如果您使用的是 xampp 7.3.9。插座已经安装。您可以检查 xampp\php\ext，您将获得 php_socket.dll。如果你得到它去你的 xampp 控制面板打开 php.ini 文件并从extension=sockets 中删除 (;) 。

Open the php.inifile in your server environment and remove ;from ;extension=sockets. if it's doesn't work, you have to download the socketextension for PHP and put it into extdirectory in the php installation path. Restart your http server and everything should work.
php.ini在您的服务器环境中打开该文件并;从;extension=sockets. 如果还是不行，就需要下载socketPHP的扩展，放到extphp安装路径下的目录下。重新启动您的 http 服务器，一切都应该正常工作。
