Good morning!

I’m trying to create a "serial" verification system with php. It would work something like this. On an X server it will store the views of the Y server; On the Y server I would only have an html template where these views would be displayed.

But for this the X Server needs to compare a key, as if it were a serial check, as well as in some desktop programs that when you buy it gets a registration key. This key would be stored on the Y server and would be fixed, the X Server will store in its own database, txt or wherever possible. several of these keys.

I apologize if I wasn’t clear, but I’ve been trying since 6:00 yesterday morning and so far I haven’t achieved anything viable. One detail, the Y server cannot know how this information is stored, it just needs to confirm that the keys match and receive the views from the X server.

        <?php

                            "!01@1-1#20-15$0-3%15");

    public function checarVersao($link){
        $ponteiro = fopen($link, "r");

        while(!feof($ponteiro)) {
            $linha = fgets($ponteiro, 4096);
            $this->client = $linha;

            if(in_array($linha, $this->server)) {
                switch($linha) {
                    case "!01@1-1#20-15$0-3%14":
                        include_once '../viw/index.php';
                        break;
                    case "!01@1-1#20-15$0-3%15":
                        include_once '../viw/erro404.php';
                        break;
                }
            } else {
                echo '<script>alert("Erro no serial");</script>';
                echo '<div id="serial-incorreto">serial incorreto! verifique o serial fornecido e tente novamente.</div>';
            }
        }
        fclose($ponteiro);
    }
}
$version = new Version();
$version->checarVersao('servidor.com.br/end/serial.txt');

?>

This is looking more like javascript than PHP, huh! Be careful with this operation

The problem is the visibility of the code between the two servers. I could not define exactly what this fits, one because php does not compile the files and is server-side, I’ve been reading about web services but I didn’t understand it very well, and it seems useless for this case.

Apparently what you want is to prevent copying or misuse of your code. If it is really that, I already say that it is useless to try these things in PHP. Any programmer with just a little bit of experience breaks this barrier without difficulty.

Well, maybe what you want to do is something like this:

Server A

$chave = 'XXXYZ';

SERVER B

$chave = 'XXXYZ';

SERVER B will be the server that returns the information of the requested external file. But all this request will have to go through the main script, not to have problems of direct access by others.

SERVER B

#request.php

$arquivo = $_GET['nome_arquivo'];

$chaveCliente = $_GET['chave'];

if ($chave === $chaveCliente) {
     include DIRETORIO_PADRAO . $arquivo . '.php';
}

SERVER TO:

 $opts = array(
      'http'=>array(
         'method'=> 'GET',
         'content' => http_build_query([
                   'chave' => $chave,
                    'nome_arquivo' => 'view_cadastro'
                  ])

       )
 );


 $dados_view = file_get_contents('http://www.servidor-b.com/request.php', false, $opts);

I do not recommend in any way this operation, but within what you asked, I tried to do in the safest way possible.
