更新用戶詳細信息，sql server 2008 sqlsrv

Question

您好我在運行腳本時遇到了一些問題，我不斷收到一條錯誤消息，說它需要兩個參數，我不知道如何修復它，繼承腳本：

<?php
session_start ();
if(isset($_SESSION['user'])){
$username = $_SESSION['username'];
if(isset($_POST['submit'])){
    $oldpassword = $_POST['oldpassword'];
    $newpassword = $_POST['newpassword'];
    $serverName = "server";
    $connectionInfo = array("Database"=>"database","UID"=>"id", "PWD"=>"pass");
    $conn = sqlsrv_connect( $serverName, $connectionInfo);
    if( $conn === false){
        echo "Error in connection.\n";
        die( print_r( sqlsrv_errors(), true));
    }
    $tsql = "SELECT userPass FROM customers WHERE userName='$username'";
    $stmt = sqlsrv_query($conn, $tsql, array(), array( "Scrollable" => 'static' ));
    if ( !$stmt ){
        die( print_r( sqlsrv_errors(), true));
    }
    $rows = sqlsrv_num_rows($stmt);
    if($rows === false){
        die( print_r( sqlsrv_errors(), true));
    }elseif($rows == 0){
        echo "No rows returned.";
        exit();
    }else{
        $querychange = sqlsrv_query("UPDATE customers SET userPass='$newpassword' WHERE userName='$username'");
        session_destroy();
        die ("Your password has been changed. <a href='index.php'>Return</a> to the main page and login with your new password.");
    }
}
}
?>

我一直收到這個錯誤

PHP警告：sqlsrv_query（）需要至少2個參數，第27行的file_name.php中給出1

第27行是我更新客戶的地方。 如果任何人都可以在腳本中發現錯誤，你可以告訴我，也是我沒有完成SQL注入，在這個階段我只是想在實現它之前讓它工作。

感謝所有的幫助，非常感謝

嘗試將連接傳遞給sqlsrv_query

就像是：

 $querychange = sqlsrv_query($conn, "UPDATE customers SET userPass='$newpassword' WHERE userName='$username'");
