SQLSRV 404找不到

Question

我将PHP连接到MSSQL而不是MySQL。 PHP在我的PC上的nginx Web服务器上运行。我已经成功连接到数据库，并能够在php中显示获取的数据，但它显示404未找到哪个是奇怪的。

here is the screenshot of the result

这是我的代码，但即使我把phpinfo（），它仍然会显示404未找到但会显示php的信息。

<?php 
class Mssql{

    private $_database = "sample";
    private $_host = "CSRMS-SVR-DB1\CSOFFICE9";
    private $_username ="sa";
    private $_password ="_pass123";

    public $con;

    public function mssql_connect(){
        $con_properties = [
            "Database" => $this->_database,
            "UID" => $this->_username,
            "PWD" => $this->_password
        ];
        $this->con = sqlsrv_connect($this->_host, $con_properties);

        if ($this->con) {
            echo "Connection Success";
        }
        else {
            die( print_r( sqlsrv_errors(), true ));
        }
    }
}

$sql = "SELECT * FROM prof";


$test = new Mssql;
$test->mssql_connect();
$result = sqlsrv_query($test->con, $sql);
$row = sqlsrv_fetch_array($result);

$someJSON = json_encode($row);
echo $someJSON;
