Json Get 1 record PHP OLEDB

Ciao a tutti sto tentando di leggere 1 record dalla mia app "richiedendo un tag nominato "pid" con uno script Php con Driver OLEDB(devo leggerlo su un DB Microsoft ACCESS) per leggerli tutti ho realizzato questo e funziona:

<?php

/* La query SQL,  */
$query="select *from tabripa" ;

/* I parametri di connessione */
$path= "D:/OneDrive/Programmazione/Android/" ;
$db_name= "dati.mdb" ;
$dsource=$path.$db_name ;
$cn_string="Provider=Microsoft.Jet.OLEDB.4.0;" ;
$cn_string.="Data Source=$dsource;" ;
$cn_string.="Jet OLEDB:Database Password=gmpa";


$response = array();

/* La connessione */
if (!file_exists($dsource) ){

die("Il database non esiste") ;

}
$cn= new COM("ADODB.Connection");
$cn->open($cn_string) ;

/* Istanziamo un oggetto Recordset
e inviamo la query attraverso
il metodo Open() */
$rs= new COM("ADODB.Recordset") ;
$rs->Open($query,$cn) ;

/* Ciclo per recuperare i valori dal recordset
EOF= tutto il set di dati è stato esaminato 
e il cursore è giunto in fondo */
if (!$rs->EOF) {
    // looping through all results
    // products node
    $response["products"] = array();
    
    while (!$rs->EOF) {
        // temp user array
        $product = array();
        $product["pid"] = $rs -> Fields["Nbusta"]->value;
        $product["name"] = $rs -> Fields["Nome"]->value;
        $product["price"] = $rs -> Fields["costo"]->value;
        $product["description"] = $rs -> Fields["riparatore"]->value;
       // $product["created_at"] = $row["created_at"];
       // $product["updated_at"] = $row["updated_at"];

	    $rs -> MoveNext();


        // push single product into final response array
        array_push($response["products"], $product);
    }
    // success
    $response["success"] = 1;

    // echoing JSON response
    echo json_encode($response);
} else {
    // no products found
    $response["success"] = 0;
    $response["message"] = "No products found";

    // echo no users JSON
    echo json_encode($response);
}

/* Chiusura Recordset (da non farsi nelle query di comando) */
$rs->Close() ;

?>

Ora devo fare l'equivalente di questo script MYSQL però in OLEDB:

<?php

/*
 * Following code will get single product details
 * A product is identified by product id (pid)
 */

// array for JSON response
$response = array();


// include db connect class
require_once __DIR__ . '/db_connect.php';

// connecting to db
$db = new DB_CONNECT();

// check for post data
if (isset($_GET["pid"])) {
    $pid = $_GET['pid'];

    // get a product from products table
    $result = mysql_query("SELECT *FROM products WHERE pid = $pid");

    if (!empty($result)) {
        // check for empty result
        if (mysql_num_rows($result) > 0) {

            $result = mysql_fetch_array($result);

            $product = array();
            $product["pid"] = $result["pid"];
            $product["name"] = $result["name"];
            $product["price"] = $result["price"];
            $product["description"] = $result["description"];
           // $product["created_at"] = $result["created_at"];
           // $product["updated_at"] = $result["updated_at"];
            // success
            $response["success"] = 1;

            // user node
            $response["product"] = array();

            array_push($response["product"], $product);

            // echoing JSON response
            echo json_encode($response);
        } else {
            // no product found
            $response["success"] = 0;
            $response["message"] = "No product found";

            // echo no users JSON
            echo json_encode($response);
        }
    } else {
        // no product found
        $response["success"] = 0;
        $response["message"] = "No product found";

        // echo no users JSON
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";

    // echoing JSON response
    echo json_encode($response);
}
?>

HO provato a fare cosi ma credo sia sbagliato:

<?php

/* La query SQL,  */


/* I parametri di connessione */
$path= "D:/OneDrive/Programmazione/Android/" ;
$db_name= "dati.mdb" ;
$dsource=$path.$db_name ;
$cn_string="Provider=Microsoft.Jet.OLEDB.4.0;" ;
$cn_string.="Data Source=$dsource;" ;
$cn_string.="Jet OLEDB:Database Password=gmpa";


$response = array();

/* La connessione */
if (!file_exists($dsource) ){

die("Il database non esiste") ;

}
$cn= new COM("ADODB.Connection");
$cn->open($cn_string) ;

/* Istanziamo un oggetto Recordset
e inviamo la query attraverso
il metodo Open() */
$rs= new COM("ADODB.Recordset") ;


if (isset($_GET["Nbusta"])) {
    $pid = $_GET['Nbusta'];
    $query="select *FROM tabripa WHERE Nbusta = $pid " ;
    // get a product from products table
    $result = $rs->Open($query,$cn) ;

/* Ciclo per recuperare i valori dal recordset
EOF= tutto il set di dati è stato esaminato 
e il cursore è giunto in fondo */
    if (!empty($result)) {
        // check for empty result

    
        if ($result->EOF) 		{
			
		while (!$result->EOF)
        // temp user array
        $product = array();
        $product["pid"] = $result -> Fields["Nbusta"]->value;
        $product["name"] = $result -> Fields["Nome"]->value;
        $product["price"] = $result -> Fields["costo"]->value;
        $product["description"] = $result -> Fields["riparatore"]->value;
       // $product["created_at"] = $row["created_at"];
       // $product["updated_at"] = $row["updated_at"];

	    $results -> MoveNext();


        // push single product into final response array
        array_push($response["products"], $product);
             // echoing JSON response
            echo json_encode($response);
        
    } else {
        // no product found
        $response["success"] = 0;
        $response["message"] = "No product found";

        // echo no users JSON
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";

    // echoing JSON response
    echo json_encode($response);
}
/* Chiusura Recordset (da non farsi nelle query di comando) */
$rs->Close() ;

/* Pulizia dell’oggetto Recordset */
//$rs->Release() ;
//$rs= null ;


}
?>[code]

Vi ringrazio in anticipo non sono un esperto si Php ho solo un po di basi,vado al Lavo ro Buona giornata a tutti.
