php driver does not work after updating xamp

I have updated XAMP to the latest version, which comes with php 7.2.

I have added the drivers to xamp / php / ext /:

php_pdo_sqlsrv_72_nts.dll
php_pdo_sqlsrv_72_nts.dll
php_sqlsrv_72_ts.dll
php_sqlsrv_72_ts.dll

I have also configured the php.ini:

extension=php_pdo_sqlsrv_72_nts_x86
extension=php_sqlsrv_72_nts_x86
extension=php_pdo_sqlsrv_72_ts_x86
extension=php_sqlsrv_72_ts_x86

Here my connection code to SQL SERVER:

<?php

$serverName = "NOWAY\SQLEXPRESS"; //serverName\instanceName
$connectionInfo = array( "Database"=>"a1", "UID"=>"root", "PWD"=>"NOWAY");
$conn = sqlsrv_connect( $serverName, $connectionInfo);

    if( $conn ) {
         echo "Conexión establecida.<br/>";
    }else{
         echo "Conexión no se pudo establecer.<br/>";
         die( print_r( sqlsrv_errors(), true));
    }
}

Finally I have this error:

  

Connection could not be established. Array ([0] = > Array ([0] => IMSSP   [SQLSTATE] = > IMSSP 1 = > -49 [code] = > -49 [2] = > This extension   Requires the Microsoft ODBC Driver for SQL Server.

I have also verified if I have installed the ODBC driver in windows

As you can see, I have attacked the situation in several ways and I still can not find the solution. How could I solve this error?
