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

    I just had to uncomment it in my php.ini; I also had to copy it from another directory to the PHP directory, but it came with the installation. – Jane Panda Jul 20 '12 at 13:16
  • Thanks Bob. i am using wamp server. First i changed in apache's php.ini and no effect. Then, i also changed in php's php.ini. At the end, websocket server started. :) – balamurugan Oct 04 '14 at 10:19
  • I have enabled `socket` extension in both php.ini but it still giving me same error. Do you guys have any idea why this would happen? – karmicdice Feb 05 '16 at 12:36

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.dll to extension=php_sockets.dll.

    The only php.ini in my directory was php.ini-production and php.ini-development, and I could not find ;extension=php_sockets.dll anywhere in those files, so I jjust wrote the line extension=php_sockets.dll in both and saved. I'm still getting the undefined function socket_create() error though, any idea? I'm using windows. – 2316354654 Jun 15 '18 at 13:59
  • @2316354654 make sure your php.ini contains this lines`extension_dir="C:\xampp\php\ext" ` – Shashank Mishra Jun 21 '18 at 10:51
  • in my case `;extension=php_sockets.dll` was missing. I added it and now its working – log0 Jul 06 '20 at 06:42

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.

Open the php.ini file in your server environment and remove ; from ;extension=sockets. if it's doesn't work, you have to download the socket extension for PHP and put it into ext directory in the php installation path. Restart your http server and everything should work.

Follow these steps if you're on openSuse or SUSE.

Install php7 if it's not already installed.

zypper in php7

If you have php7 installed, update it with:

zypper update php7

Install php7-sockets

zypper in php7-sockets

Sometimes the version of your xampp (wamp or ...) is different with CLI. I suggest first using php --ini to find that use a correct version.

Moreover to solve this problem, you can open your xampp and use shell.

I got this error when my .env file was not set up properly. Make sure you have a .env file with valid database login credentials.

  • this looks like a solution for at specific situation, and not a general solution. .env files are not necessarily a standard for a php application... – JoSSte Jan 29 '22 at 20:36
