This can be done by establishing the Socket communication between PHP and Matlab

Example code for it:

Code for PHP:

<?php 
$host    = "127.0.0.1";
$port    = 5002;
$data = array(
    'username' => 'codexworld',
    'password' => '123456'
);
$payload = json_encode($data);

$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");    
$result = socket_connect($socket, $host, $port) or die("Could not connect to server\n");  
socket_write($socket, utf8_encode($payload), strlen($payload)) or die("Could not send data to server\n");

$response = socket_read($socket, 8);

echo $response;
socket_close($socket);
?> 

Code for MATLAB:

server = tcpserver("127.0.0.1",5002,"ConnectionChangedFcn",@connectionFcn)

function connectionFcn(src, ~)
if src.Connected
    disp("Client connected")
    rawData = read(src,src.NumBytesAvailable,'uint8');
    jsonString = native2unicode(rawData, 'ISO-8859-1');
    disp(jsonString);
    structValues=jsondecode(jsonString);
    disp(structValues);
    result=56;
    write(src,result,"int8");
end
end

Output PHP:

Output MATLAB:
