PHP socket error connecting device

I have a ZK F7 attendance machine with TCP/IP port which returns data through the software comes with it. But I want to collect attendance data through php using php socket in an array then save them in mysql. to do this I tried the code bellow but getting erro (call to undefined function socket_create()). what should be the solve of the error?

<?php

// Server IP address
$address = "192.168.1.201";

// Port to listen
$port = 4370;

$mysock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($mysock,$address, $port) or die('Could not bind to address');
socket_listen($mysock, 5);
$client = socket_accept($mysock);

// read 1024 bytes from client
$input = socket_read($client, 1024);

// write received gprs data to the file
writeToFile('socketLog.txt', $input);

socket_close($client);
socket_close($mysock);

function writeToFile($strFilename, $strText) {
    if($fp = @fopen($strFilename,"w")) {
        $contents = fwrite($fp, $strText);
        fclose($fp);
        return true;
    } else {
        return false;
    }
}
?>

Change the line

$mysock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

to 

$mysock = socket_create(AF_INET, SOCK_DGRAM, 0);

And I guess that will fix it by using UDP to connect to the ZK device.

You don't have php_sockets extension enabled. Go do that in php.ini
