php - Fatal error: Call to undefined function socket_create()

Question

My code is like this:

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 )

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 .

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

You'll need to install (or enable) the Socket PHP extension: http://www.php.net/manual/en/sockets.installation.php
