PHP connect to SQL Server 2014

I have tried to connect SQL Server by using PHP for both PDO and also simple connection. But some how there is always error occures. Here are my scripts by using PDO and also simple connection.

$serverName = "Server"; //serverName\instanceName
$connectionInfo = array( "Database"=>"Database", "UID"=>"Username", "PWD"=>"Password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
    echo "Connection established.<br />";
    $resultfile = fopen("E:\\result.txt", "w") or die("Unable to open file!");
    fwrite($resultfile, "wew");
    fclose($resultfile); 
}else{
    echo "Connection could not be established.<br />";
    $resultfile = fopen("E:\\result.txt", "w") or die("Unable to open file!");
    fwrite($resultfile , print_r( sqlsrv_errors(), true));
    fclose($resultfile ); 
    die( print_r( sqlsrv_errors(), true));
}

Using simple connection :

try  
    {  
        $conn = new PDO( "sqlsrv:server = $serverName; Database = Database", "password", "username");  
        $conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ); 
        echo "Connection established.<br />";
        $resultfile = fopen("E:\\result.txt", "w") or die("Unable to open file!");
        fwrite($resultfile, "wew");
        fclose($resultfile); 
    }  
    catch(Exception $e)  
    {   $resultfile = fopen("E:\\result.txt", "w") or die("Unable to open file!");
        fwrite($resultfile, "wew");
        fclose($resultfile);  
        die( print_r( $e->getMessage() ) );   
    }

And here are the error result by PDO:

    ))

Simple connection:

SQLSTATE[08001]: [Microsoft][ODBC Driver 13 for SQL Server]Encryption not supported on the client.

I still don't understand why I cannot connect because I am using the latest SQL Server Driver for PHP 7.2.5.
