Great Tutorial, just one change, You unset the socket and then use it in the next line, needs to be other way round and then return i believe.

if ($input == null)
{
//zero length string meaning disconnected, remove and close the socket
unset($client_socks[$i]);
socket_close($client_socks[$i]);
}

Thank you for this great tutorial.
I have a small issue after running the code.
When I open the telnet client and try to enter only one litter it response instantly even before I click enter
it responses after pressing any key not only enter
I thought the problem was in the code but I pasted your code in my project and tried it but the same problem.
I hope you help me.
note: I was running the script from the browser not the terminal.

Hii Sir, how can I start a socket server on a host server.I am using shared server

Dear you have write the Client side socket script on the start. As we know that the PHP is the server scripting language so how after loading on to the client server it will run to connect to the server script on the server side.

Fatal error: Uncaught Error: Call to undefined function socket_create() in E:\Web\Xampp\htdocs\index.php:2 Stack trace: #0 {main} thrown in E:\Web\Xampp\htdocs\index.php on line 2

Obviously, sockets don’t exist anymore xD
